SN74LVC1T45DRLR is a Texas Instruments single-bit dual-supply bus transceiver with configurable voltage translation - for bridging mismatched logic domains on space-constrained boards: both VCCA and VCCB operate over the full 1.65V to 5.5V range, SOT-5X3 (DRL) 6-pin package (1.60mm x 1.20mm), plus-minus 24mA output drive at 3.3V, up to 420Mbps when translating 3.3V to 5V, -40C to 85C. The fully configurable dual-rail design translates between any standard nodes (1.8V, 2.5V, 3.3V, 5V) without external direction glue, so mixed-voltage designs drop a discrete level-shifter network; Ioff circuitry and VCC isolation put both ports in high-impedance when either supply is down, preventing backflow damage during partial power-down sequencing. Business impact: one SOT-5X3 device replaces a FET-plus-resistor discrete shifter, cutting placement cost and board area on every mixed-voltage interface - the DIR pin selects direction with a single logic level. Selection advice: the DRLR suffix is the SOT-5X3 tape-and-reel packing - for SC70 consider the DCKR variant, for DSBGA the YZPR; verify the DIR pin is driven by VCCA-referenced logic and that both supplies stay within 1.65V to 5.5V.

State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.
SN74LVC1T45DRLR is a Voltage-level translator from Texas Instruments, orderable in the SOT-5X3 (DRL) 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.
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.

Browse existing catalog records — same series first, then the same category and manufacturer. These are not confirmed replacements; compatibility requires engineering review.
Every suffix in a manufacturer ordering code identifies one exact orderable device — package, temperature grade, packing format or a revision. SN74LVC1T45DRLR names the SOT-5X3 (DRL) configuration; a code that differs by even one suffix character may be a different device. Always quote the complete code exactly as it appears on your BOM.
The package (SOT-5X3 (DRL)) 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.
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.
