Nexperia · Logic Gates · SOT-353

74AHCT1G32GW from Nexperia, in a SOT-353. 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 Data input B; inputs are overvoltage tolerant to 5.5 V and the 74AHCT1G32 uses TTL input levels.
2 A input Data input A; inputs are overvoltage tolerant to 5.5 V and the 74AHCT1G32 uses TTL input levels.
3 GND power_in Ground (0 V) reference for all voltages in the datasheet.
4 Y output Data output Y, the OR of inputs A and B; output current limited to ±25 mA per the limiting values.
5 VCC power_in Supply voltage; recommended range 4.5 V to 5.5 V for the 74AHCT1G32, absolute maximum -0.5 V to +7.0 V.
