UTC Unisonic Tech · Logic Gates · SOT-23-5

U74AHC1G08G-AE5-R from UTC Unisonic Tech, in a SOT-23-5. 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 Logic input A of the 2-input AND gate; recommended input voltage range is 0 to 5.5 V, with an absolute maximum of -0.5 to 7 V.
2 B input Logic input B of the 2-input AND gate; recommended input voltage range is 0 to 5.5 V, with an absolute maximum of -0.5 to 7 V.
3 GND power_in Ground reference; the VCC or GND current is rated at ±50 mA absolute maximum.
4 Y output AND gate output (Y = A·B); output voltage is limited to 0 to VCC, with output current rated at ±25 mA absolute maximum.
5 VCC power_in Positive supply; recommended range is 2 to 5.5 V, with an absolute maximum of -0.5 to 7 V.
