onsemi · Gates · SC-74A-5

MC74HC1G02DBVT1G from onsemi, in a SC-74A-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 B input Logic input B of the 2-input NOR gate. CMOS input with high noise immunity; VIH ≥ 0.7·VCC (e.g. 3.15 V at VCC = 4.5 V), VIL ≤ 0.3·VCC. Input leakage ±1.0 μA max at VIN = 6.0 V.
2 A input Logic input A of the 2-input NOR gate. CMOS input with high noise immunity; VIH ≥ 0.7·VCC (e.g. 3.15 V at VCC = 4.5 V), VIL ≤ 0.3·VCC. Input leakage ±1.0 μA max at VIN = 6.0 V.
3 GND power_in Ground / VSS reference (0 V). Maximum DC current per ground pin ±25 mA.
4 Y output NOR gate output Y = NOT(A OR B). Symmetrical CMOS push-pull output, IOH = IOL = 2 mA at VCC = 4.5 V (half the drive of standard MC74HC series).
5 VCC power_in Positive supply, 2.0 V to 6.0 V recommended (absolute max 6.5 V for SC-74A). Decouple with a local 100 nF ceramic to GND. Maximum DC supply current per pin ±25 mA.
