UTC Unisonic Tech · Gates · SOP-14

U74HC08G from UTC Unisonic Tech, in a SOP-14. 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 1A input Gate 1 input A. CMOS logic input, VIH ≥ 0.7·VCC, VIL ≤ 0.3·VCC. Input leakage ±100 nA (max) at VCC = 6 V.
2 1B input Gate 1 input B. CMOS logic input paired with 1A to produce output 1Y = 1A · 1B.
3 1Y output Gate 1 output. Push-pull CMOS output, Y = A · B. Drive capability 4 mA at VCC = 4.5 V, 5.2 mA at VCC = 6 V.
4 2A input Gate 2 input A. CMOS logic input.
5 2B input Gate 2 input B. CMOS logic input.
6 2Y output Gate 2 output. Y = A · B.
7 GND power_in Ground reference (0 V).
8 3Y output Gate 3 output. Y = A · B.
9 3A input Gate 3 input A. CMOS logic input.
10 3B input Gate 3 input B. CMOS logic input.
11 4Y output Gate 4 output. Y = A · B.
12 4A input Gate 4 input A. CMOS logic input.
13 4B input Gate 4 input B. CMOS logic input.
14 VCC power_in Positive supply, 2 V to 6 V operating range (absolute max -0.5 V to 7 V). Quiescent current ICC = 2 µA (max) at VCC = 6 V.
