SN74AHCT1G08DCKR

UMW · Gates · SC-70-5

SN74AHCT1G08DCKR from UMW, in a SC-70-5. 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 A input Logic input A of the 2-input AND gate. TTL-compatible input; VIH min 2 V, VIL max 0.8 V at VCC = 4.5-5.5 V. Absolute maximum input voltage range -0.5 V to +7.0 V.
2 B input Logic input B of the 2-input AND gate. TTL-compatible input; VIH min 2 V, VIL max 0.8 V at VCC = 4.5-5.5 V. Absolute maximum input voltage range -0.5 V to +7.0 V.
3 GND power_in Ground reference (0 V) for the device. Absolute maximum DC ground current per supply pin ±50 mA.
4 Y output AND-gate logic output, Y = A · B. Drives ±8 mA at VCC = 5 V; VOH ≥ 3.8 V at IOH = -8 mA, VOL ≤ 0.44 V at IOL = 8 mA (over full temperature range).
5 VCC power_in Positive supply voltage. Recommended operating range 4.5 V to 5.5 V (absolute maximum 7.0 V). Typical ICC 1.0 µA, max 10 µA (VIN = VCC or GND, IO = 0).
