TXS0102DTTR

Texas Instruments

TXS0102DTTR is a Texas Instruments TXS0102 2-bit bidirectional voltage-level translator in X1SON-8, 5000-piece tape and reel — VCCA 1.65 V to 3.6 V, VCCB 2.3 V to 5.5 V (VCCA at or below VCCB), automatic direction sensing with no direction pin, OE enable referenced to VCCA, works with open-drain and push-pull signals, −40 °C to +85 °C. The DTTR code is the selection point: the 1 × 1 mm X1SON package on 5000-piece reel — the absolute smallest, highest-volume order code in the TXS0102 family, for level shifting inside modules and chip-scale designs. Selection advice: pick the DTTR only when the assembly flow is proven for 1 × 1 mm leadless parts — inspection and rework are essentially impossible by hand, so keep a VSSOP DCU code as the bring-up alternate on the same schematic. The 5000-piece reel is the deepest-volume packing TI offers here. Evidence: TI carrier material report for TXS0102DTTR confirms X1SON-8 (DTT), 5000-piece reel. Match the full TXS0102DTTR code.

SELECTION GUIDANCE

TXS0102DTTR selection guidance

TXS0102DTTR is a TXS0102 from Texas Instruments, orderable in the X1SON-8 package. The ordering code fixes the exact configuration you receive — package, grade and packing — so procurement starts with matching this code character-for-character against your BOM, not just the base series name.

Within the same series, also consider: TXS0102DCTR — package SSOP-8; packing LARGE T&R; Package/pins: SSOP (DCT), 8 pins; TXS0102DQER is X2SON (DQE), 8 pins; do not assume direct replacement — verify PCB pads, thermal and pinout; factory packing is LARGE T&R, 3,000 per pack; TXS0102DQER is LARGE T&R, 5,000 per pack. · TXS0102DCTT — package SSOP-8; packing SMALL T&R; Package/pins: SSOP (DCT), 8 pins; TXS0102DQER is X2SON (DQE), 8 pins; do not assume direct replacement — verify PCB pads, thermal and pinout; factory packing is SMALL T&R, 250 per pack; TXS0102DQER is LARGE T&R, 5,000 per pack. · TXS0102DCUR — package VSSOP-8; packing LARGE T&R; Package/pins: VSSOP (DCU), 8 pins; TXS0102DQER is X2SON (DQE), 8 pins; do not assume direct replacement — verify PCB pads, thermal and pinout; factory packing is LARGE T&R, 3,000 per pack; TXS0102DQER is LARGE T&R, 5,000 per pack. · TXS0102DCUT — package VSSOP-8; packing SMALL T&R; Package/pins: VSSOP (DCU), 8 pins; TXS0102DQER is X2SON (DQE), 8 pins; do not assume direct replacement — verify PCB pads, thermal and pinout; factory packing is SMALL T&R, 250 per pack; TXS0102DQER is LARGE T&R, 5,000 per pack.. These variants share the core design; pick the code whose package and packing match your assembly process and reel requirements. If your BOM lists one of these instead of TXS0102DTTR, do not substitute without checking the exact ordering code — even one suffix character can change the device you receive.

When you request a quote, include the full ordering code, the target packing format (reel, tube, tray or cut tape), your quantity and any date-code or lot requirements. We reconfirm manufacturer, suffix, package, date code and traceability against the actual offered lot before any commercial quote is issued, and every RFQ gets a reply within 24 hours.

COMMON QUESTIONS

TXS0102DTTR FAQ

What is the difference between TXS0102DTTR and TXS0102DCTR, TXS0102DCTT, TXS0102DCUR?

These are order-code variants of the same Texas Instruments series. They share the core design; the ordering code selects the exact configuration — TXS0102DCTR: Package/pins: SSOP (DCT), 8 pins; TXS0102DQER is X2SON (DQE), 8 pins; do not assume direct replacement — verify PCB pads, thermal and pinout; factory packing is LARGE T&R, 3,000 per pack; TXS0102DQER is LARGE T&R, 5,000 per pack.; TXS0102DCTT: Package/pins: SSOP (DCT), 8 pins; TXS0102DQER is X2SON (DQE), 8 pins; do not assume direct replacement — verify PCB pads, thermal and pinout; factory packing is SMALL T&R, 250 per pack; TXS0102DQER is LARGE T&R, 5,000 per pack.; TXS0102DCUR: Package/pins: VSSOP (DCU), 8 pins; TXS0102DQER is X2SON (DQE), 8 pins; do not assume direct replacement — verify PCB pads, thermal and pinout; factory packing is LARGE T&R, 3,000 per pack; TXS0102DQER is LARGE T&R, 5,000 per pack.. TXS0102DTTR itself is the X1SON-8 configuration. A code that differs by even one character may be a different device, so always quote the complete code exactly as it appears on your BOM.

What is the difference between package and packing for TXS0102DTTR?

The package (X1SON-8) is the physical form of the device itself. Packing describes how the devices are delivered — reel, tube, tray or cut tape. The same ordering code can ship in different packing formats depending on the lot, so confirm the required packing format when you submit your RFQ.

Can you provide traceability documents for TXS0102DTTR?

Traceability evidence — lot and date-code information, labels and photos — is confirmed per lot at quotation time, because it depends on the actual lot offered. Tell us which documents your receiving inspection requires when you submit the RFQ, and we will confirm what can be provided for the offered lot.

How do I request a quotation for TXS0102DTTR?

Add TXS0102DTTR to your RFQ with the complete ordering code, the manufacturer (Texas Instruments), your quantity, the target packing format and any date-code requirements. We reply to every RFQ within 24 hours.
