This covers the common logic voltage domains from 1.2 V and 1.8 V up through 3.3 V and 5 V, so a single device bridges a 1.8 V microcontroller to a 3.3 V sensor or a 3.3 V FPGA to a 5 V peripheral without needing a direction-control pin. The bidirectional architecture uses an auto-sense topology — the output driver engages based on the input signal edge, so the same pin handles both transmit and receive. This eliminates the routing overhead of a dedicated direction line and simplifies PCB layout for I2C, SPI, UART, or GPIO interfaces where the signal direction changes dynamically. ## Supply voltage flexibility and temperature range Both VCCA and VCCB accept 1.1 V to 5.5 V independently, so the translator works with any combination of low-voltage and legacy logic rails. The 1.1 V floor supports the latest sub-1.2 V cores and memory interfaces, while the 5.5 V ceiling covers standard 5 V TTL and CMOS peripherals without external level shifting. The -40°C to 125°C operating temperature range qualifies the part for industrial control cabinets, automotive cabin electronics, and outdoor telecom equipment where the ambient temperature swings beyond the commercial 85°C limit. The SOT-23-6 package keeps the footprint small enough for space-constrained designs like sensor modules or portable instruments. ## Active lifecycle and compliance status The part is supplied in Tape & Reel (TR) or Cut Tape (CT) packaging, which suits both automated pick-and-place assembly and prototype hand-assembly quantities. No pin-compatible second source or successor is recorded — the 74LXC family is the current generation from TI for this function.","metaTitle":"SN74LXC1T45DBVR TI Level Translator, 420 Mbps, SOT-23-6","metaDescription":"Texas Instruments SN74LXC1T45DBVR bidirectional voltage level translator, 420 Mbps data rate, 1.1-5.5 V dual supply, SOT-23-6.","metaKeywords":null},"attributes":{"series":"74LXC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"74LXC","Package":"Tape & Reel (TR); Cut Tape (CT)","Data Rate":"420Mbps","Output Type":"Non-Inverted","Channel Type":"Bidirectional","Mounting Type":"Surface Mount","Package / Case":"SOT-23-6","Voltage - VCCA":"1.1 V ~ 5.5 V","Voltage - VCCB":"1.1 V ~ 5.5 V","Translator Type":"Voltage Level","lifecycle_stage":"eol_hot","Number of Circuits":"1","Channels per Circuit":"1","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"SOT-23-6"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.61","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.61000","currency":"USD"},{"qty":10,"price":"$0.53300","currency":"USD"},{"qty":25,"price":"$0.50080","currency":"USD"},{"qty":100,"price":"$0.40880","currency":"USD"},{"qty":250,"price":"$0.37976","currency":"USD"},{"qty":500,"price":"$0.32320","currency":"USD"},{"qty":1000,"price":"$0.25856","currency":"USD"},{"qty":3000,"price":"$0.23432","currency":"USD"},{"qty":6000,"price":"$0.21816","currency":"USD"},{"qty":15000,"price":"$0.21008","currency":"USD"},{"qty":30000,"price":"$0.20200","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/677ecc27015c1b59bd1564b91c5440ee.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What supply voltages does the SN74LXC1T45DBVR support?","answer":"Both VCCA and VCCB accept 1.1 V to 5.5 V independently, so the translator bridges any combination of 1.2 V, 1.8 V, 2.5 V, 3.3 V, or 5 V logic rails without external level shifting."},{"question":"What is the maximum data rate of the SN74LXC1T45DBVR?","answer":"The device supports data rates up to 420 Mbps, which covers high-speed SPI, UART, and GPIO interfaces.
