SN74AHC1G02DCKT

Texas Instruments · Logic Gates · SC-70-5

SN74AHC1G02DCKT from Texas Instruments, 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 A input Input A of the single 2-input positive-NOR gate, with Schmitt trigger action and inputs tolerant to 5.5 V.
2 B input Input B of the single 2-input positive-NOR gate, with Schmitt trigger action and inputs tolerant to 5.5 V.
3 GND power_in Ground pin for the device.
4 Y output Output Y of the NOR gate (Y = A + B in positive logic), rated for ±8 mA output drive at 5 V.
5 VCC power_in Supply pin; the device operates from 2 V to 5.5 V.
