MC74VHC1G32DFT2G

onsemi · Logic Gates · SC-70-5

MC74VHC1G32DFT2G 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; the input structure is over-voltage tolerant up to 5.5 V regardless of the supply voltage.
2 A input Input A of the 2-input OR gate; the input structure is over-voltage tolerant up to 5.5 V regardless of the supply voltage.
3 GND power_in Ground reference pin (0 V).
4 Y output OR gate output (Y = A OR B); the output source/sink current is rated at ±25 mA maximum (absolute maximum rating).
5 VCC power_in Positive supply pin; the device is designed for 2.0 V to 5.5 V VCC operation.
