74LVCH2T45DC

Nexperia · Translators, Level Shifters · VSSOP-8-0.5mm

74LVCH2T45DC from Nexperia, 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 VCC(A) power_in Supply voltage for port A and DIR, specified from 1.2 V to 5.5 V.
2 1A bidirectional Data input or output referenced to VCC(A); inputs accept up to 5.5 V and the port goes high-impedance when either supply is at GND level (suspend mode).
3 2A bidirectional Data input or output referenced to VCC(A); inputs accept up to 5.5 V and the port goes high-impedance when either supply is at GND level (suspend mode).
4 GND power_in Ground reference at 0 V for the device.
5 DIR input Direction control referenced to VCC(A); HIGH allows transmission from nA to nB and LOW allows transmission from nB to nA.
6 2B bidirectional Data input or output referenced to VCC(B); inputs accept up to 5.5 V and the port goes high-impedance when either supply is at GND level (suspend mode).
7 1B bidirectional Data input or output referenced to VCC(B); inputs accept up to 5.5 V and the port goes high-impedance when either supply is at GND level (suspend mode).
8 VCC(B) power_in Supply voltage for port B, specified from 1.2 V to 5.5 V.
