74LVC1T45GM

Nexperia · Translators / Level Shifters · XSON-6(1x1.5)

74LVC1T45GM from Nexperia, in a XSON-6(1x1.5). 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 VCC(A) power_in Supply voltage for port A and DIR, specified from 1.2 V to 5.5 V.
2 GND power_in Ground reference at 0 V; the device enters suspend mode when VCC(A) or VCC(B) is at GND level.
3 A bidirectional Data input or output on the VCC(A)-referenced port, with inputs accepting voltages up to 5.5 V.
4 B bidirectional Data input or output on the VCC(B)-referenced port, with outputs in high-impedance OFF-state in suspend mode.
5 DIR input Direction control referenced to VCC(A): HIGH transmits A to B, LOW transmits B to A.
6 VCC(B) power_in Supply voltage for port B, specified from 1.2 V to 5.5 V.
