MC74VHC1GT14DBVT1G

onsemi · Inverters · SC-74A-5

MC74VHC1GT14DBVT1G from onsemi, in a SC-74A-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 NC unconnected No connection; the datasheet lists this pin as NC with no function assigned.
2 A input Single Schmitt-trigger inverter input; DC input voltage is specified from 0 V to 5.5 V, regardless of the supply voltage.
3 GND power_in Ground reference pin for the device.
4 Y output Inverted output; in active mode (high or low state) the output voltage is specified from 0 V to VCC, and in power-down mode (VCC = 0 V) from 0 V to 5.5 V.
5 VCC power_in Positive supply pin; recommended operating range is 2.0 V to 5.5 V.
