Texas Instruments · Translators, Level Shifters · VSSOP-8

SN74LXC2T45DCUR from Texas Instruments, in a VSSOP-8. 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 VCCA power_in Port A power supply voltage; range 1.1V to 5.5V
2 A1 bidirectional Input/Output A1 referenced to VCCA; integrated dynamic pull-down to GND when disabled
3 A2 bidirectional Input/Output A2 referenced to VCCA; integrated dynamic pull-down to GND when disabled
4 GND power_in Ground (substrate reference)
5 DIR input Direction control signal referenced to VCCA; high enables A to B transfer, low enables B to A transfer; integrated 5MΩ static pull-down to GND
6 B2 bidirectional Input/Output B2 referenced to VCCB; integrated dynamic pull-down to GND when disabled
7 B1 bidirectional Input/Output B1 referenced to VCCB; integrated dynamic pull-down to GND when disabled
8 VCCB power_in Port B power supply voltage; range 1.1V to 5.5V
