U74AHC1G02G-AE5-R

UTC Unisonic Tech · Gates · SOT-23-5

U74AHC1G02G-AE5-R from UTC Unisonic Tech, in a SOT-23-5. 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 NOR gate. CMOS input, VIH = 3.85 V min @ VCC = 5.5 V; VIL = 1.65 V max @ VCC = 5.5 V. Input leakage ±0.1 μA, CIN ~4 pF.
2 B input Logic input B of the 2-input NOR gate. CMOS input with same thresholds as A; unused inputs must be tied to VCC or GND for proper operation.
3 GND power_in Ground reference (0 V) for the device. VCC or GND current rated ±50 mA absolute maximum.
4 Y output NOR gate output, Y = NOT(A + B). CMOS push-pull output; VOH ≥ 3.94 V @ VCC = 4.5 V, IOH = -8 mA; VOL ≤ 0.36 V @ VCC = 4.5 V, IOL = 8 mA. Continuous output current ±25 mA max.
5 VCC power_in Positive supply voltage. Recommended operating range 2.0 V to 5.5 V (typ 5.0 V). Absolute maximum -0.5 V to 7 V. Quiescent supply current IQ ≤ 1 μA @ VCC = 5.5 V.
