SN74LVC1T45DBVRE4

Texas Instruments · Translators, Level Shifters · SOT-23-6

SN74LVC1T45DBVRE4 from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCCA power_in System 1 power supply voltage operating from 1.65V to 5.5V
2 GND power_in Device ground
3 A bidirectional Port A bidirectional I/O with output level referenced to VCCA
4 B bidirectional Port B bidirectional I/O with input threshold referenced to VCCB
5 DIR input Direction control input; low level selects B-to-A transmission path, high level selects A-to-B transmission path
6 VCCB power_in System 2 power supply voltage operating from 1.65V to 5.5V
