onsemi · Gates · SC-74A-5

MC74VHC1GT02DBVT1G 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 B input Gate input B; tolerates up to 5.5 V regardless of supply voltage (TTL-level thresholds on the MC74VHC1GT02).
2 A input Gate input A; tolerates up to 5.5 V regardless of supply voltage (TTL-level thresholds on the MC74VHC1GT02).
3 GND power_in Ground pin (0 V reference).
4 Y output NOR gate output (Y = NOT(A OR B)), sources/sinks 8 mA at 3.0 V and is protected when VCC = 0 V.
5 VCC power_in Positive supply voltage, 2.0 V to 5.5 V recommended operating range.
