MC74VHC1G32DFT1G

onsemi · Gates · SC-70-5

MC74VHC1G32DFT1G from onsemi, in a SC-70-5. 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 B input Input B of the 2-input OR gate; input structures tolerate voltages up to 5.5 V regardless of the supply voltage.
2 A input Input A of the 2-input OR gate; input structures tolerate voltages up to 5.5 V regardless of the supply voltage.
3 GND power_in Ground reference for the device.
4 Y output OR gate output (Y = A OR B); some output structures protect the device when VCC = 0 V and the output voltage exceeds VCC.
5 VCC power_in Positive supply, designed for 2.0 V to 5.5 V VCC operation.
