ULN2003AN

ULN2003ADYYR is a Texas Instruments seven-channel Darlington transistor array in SOT-23-THN-16, large tape and reel — for driving relays, solenoids and low-side loads from logic outputs. Seven integrated Darlington pairs with freewheeling diodes is the selection point: one chip replaces seven transistor-plus-diode circuits. Selection advice: the DYYR suffix denotes the thin SOT-23 package in large tape and reel for production — for through-hole or easier rework, the PDIP ULN2003AN suits prototypes. Each channel sinks up to 500 mA; stay within the package thermal limits when driving multiple channels simultaneously. Parameters verified against the TI official product page.

ULN2003ANSR is a Texas Instruments seven-channel Darlington transistor array in SOP-16, large tape and reel — for driving relays, solenoids and low-side loads from logic outputs. Seven integrated Darlington pairs with freewheeling diodes is the selection point: one chip replaces seven transistor-plus-diode circuits. Selection advice: the ANSR suffix denotes SOP-16 in large tape and reel — the standard SMT production variant, a balance between the compact SOT-23 DYYR and the hand-solderable PDIP AN. Each channel sinks up to 500 mA; watch total package dissipation with multiple channels on. Parameters verified against the TI official product page.

ULN2003APWR is a Texas Instruments seven-channel Darlington transistor array in TSSOP-16, large tape and reel — for driving relays, solenoids and low-side loads from logic outputs. Seven integrated Darlington pairs with freewheeling diodes is the selection point: one chip replaces seven transistor-plus-diode circuits. Selection advice: the PWR suffix denotes TSSOP-16 in large tape and reel — the most compact production variant of the ULN2003A; watch thermal derating in the thin package when multiple 500 mA channels run simultaneously. For hand-solderable builds, the PDIP ULN2003AN is the alternative. Parameters verified against the TI official product page.

CD4017BE is a CMOS decade counter and divider from Texas Instruments in a 16-pin PDIP package — for LED chasers, sequencers, frequency dividers and event counters. Its advantage is the decoded 10-output structure: one clock in, ten sequential outputs out, with no microcontroller or firmware needed for simple sequencing tasks. Selection advice: the BE suffix denotes the PDIP-16 through-hole package — the CD4017B also ships in SOIC and TSSOP, so match the full CD4017BE code to your assembly process. CMOS logic runs on a wide supply range but verify your actual VDD against the datasheet, and note that outputs drive limited current — buffer them for relays or bright LEDs. Parameters verified against the TI official product page. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

CD4051BE is a Texas Instruments 20 V 8:1 single-channel analog multiplexer/demultiplexer in 16-pin PDIP — for routing analog signals: sensor selection, audio switching and test fixtures. The 20 V analog range is the selection point: handling signals far beyond the logic supply that modern low-voltage muxes cannot. Selection advice: the BE suffix denotes PDIP-16 — the breadboard-friendly variant; for SMT, the SOIC/TSSOP variants are the pick. Mind the higher on-resistance versus modern muxes when driving low-impedance loads. TI lists this order code as Active. Parameters verified against the TI official product page. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

CD4052BE is a Texas Instruments dual 4-channel (4:1) analog multiplexer with logic-level conversion in PDIP-16 — for routing two independent analog signal groups: stereo audio switching and dual-sensor selection. Two 4:1 muxes in one package is the selection point: paired signal routing (e.g., stereo) with one control set. Selection advice: the BE suffix denotes PDIP-16 — the breadboard-friendly variant; for SMT, the SOIC/TSSOP variants are the pick. 125 ohm typical on-resistance at 15 V — mind it when driving low-impedance loads. TI lists this part as ACTIVE. Parameters verified against the TI official product page. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

CD4511BE is a Texas Instruments CMOS BCD-to-7-segment latch decoder driver for common-cathode LED displays in 16-pin PDIP — for driving 7-segment displays from BCD: counters, panel meters and clocks. The integrated latch plus segment drivers is the selection point: BCD in, display out, with no MCU multiplexing. Selection advice: the BE suffix denotes PDIP-16 — the breadboard-friendly variant; note it drives common-cathode displays only (the CD4510/CD4543 cover other configurations). TI lists this order code as Active (In Stock). Parameters verified against the TI official product page. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

SN74HC595N is a Texas Instruments 8-bit serial-in parallel-out shift register with 3-state outputs in PDIP-16, tube — for expanding MCU outputs on breadboards and prototypes: LED matrices, relay banks and 7-segment displays. Three pins driving unlimited cascaded outputs is the selection point: GPIO expansion at cents per pin. Selection advice: the N suffix denotes PDIP-16 in tube — the hand-solder-friendly variant for prototypes and education; for SMT production, the D (SOIC) or PW (TSSOP) variants are the pick. 24 MHz clock covers most display multiplexing. Parameters verified against the TI official product page. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ADS7846 is a Texas Instruments 4-wire resistive touch screen controller in 16-pin TSSOP — the industry-standard part behind two decades of PDAs, point-of-sale terminals and portable instruments: 2.2 V to 5.25 V operation, internal 2.5 V reference, direct battery measurement from 0 V to 6 V, on-chip temperature and touch-pressure measurement, SPI/QSPI 3-wire interface, auto power-down, under 0.75 mW typical at 2.7 V, 125 kHz throughput, -40 to +85 °C. The pin-compatible upgrade path is the selection point: it drops into ADS7843 sockets with only software changes, adding battery and temperature measurement the older part lacks — which is why it remains the default choice for resistive-touch retrofits and long-life industrial designs. Selection advice: for new designs needing 1.5 V digital I/O, the TSC2046 on this site is the pin-compatible successor; the TSSOP-16 is the standard package, with QFN-16 and VFBGA-48 for space-constrained boards. Parameters verified against Texas Instruments documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

AM2434BSDFHIALVR is a Texas Instruments Sitara AM243x high-performance MCU: up to four 800 MHz Arm Cortex-R5F cores, a 400 MHz Cortex-M4F, and dual gigabit PRU-ICSSG industrial-communication subsystems in a 441-ball FCBGA (17.2 x 17.2 mm). It is TI's consolidation play for factory automation — the R5F cluster delivers deterministic servo-loop control while the PRU-ICSSG runs full protocol stacks for EtherCAT target, PROFINET device and EtherNet/IP adapter on the same silicon, replacing architectures that needed an MCU plus an external industrial-Ethernet ASIC or FPGA. Heat evidence: the AM243x is TI's mainstream platform for servo drives and remote I/O modules, and its datasheet remains under active revision (Rev. J, 2026), signaling continued TI investment in the family. Selection advice: the full orderable encodes silicon revision, feature configuration, temperature grade and the ALV 441-ball FCBGA package on tape and reel — match it character-for-character; the ALX 293-ball FCCSP is a smaller, footprint-incompatible alternative, and R5F count plus PRU features vary across AM2431/32/34. Parameters verified against Texas Instruments documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.
