SN74LVC1T45DB

lingxingic · Translators, Level Shifters · SOT-23-6

SN74LVC1T45DB from lingxingic, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCC(A) power_in Supply voltage A (port A and DIR); recommended operating range 1.2V to 5.5V
2 GND power_in Ground (0V)
3 A bidirectional Data input or output for port A with 3-state capability; direction controlled by DIR input
4 B bidirectional Data input or output for port B with 3-state capability; direction controlled by DIR input
5 DIR input Direction control input; HIGH enables A to B transmission, LOW enables B to A transmission
6 VCC(B) power_in Supply voltage B (port B); recommended operating range 1.2V to 5.5V
