SN74LVC2T45QDCURQ1

Texas Instruments · Translators, Level Shifters · VSSOP-8-0.5mm

SN74LVC2T45QDCURQ1 from Texas Instruments, in a VSSOP-8-0.5mm. 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 A port power supply voltage, operating range 1.65V to 5.5V.
2 A1 bidirectional Data input/output A1 referenced to VCCA; functions as input or output depending on DIR control.
3 A2 bidirectional Data input/output A2 referenced to VCCA; functions as input or output depending on DIR control.
4 GND power_in Ground reference for the device.
5 DIR input Direction control input referenced to VCCA; high level enables data transmission from A to B, low level enables transmission from B to A.
6 B2 bidirectional Data input/output B2 referenced to VCCB; functions as input or output depending on DIR control.
7 B1 bidirectional Data input/output B1 referenced to VCCB; functions as input or output depending on DIR control.
8 VCCB power_in B port power supply voltage, operating range 1.65V to 5.5V.
