SN74HCT32DR from Texas Instruments, in a SOIC-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. TTL-compatible logic input; VIH >= 2 V, VIL <= 0.8 V at VCC = 4.5-5.5 V. Input hold current ±100 nA typical (±1 µA max).
2 1B input Gate 1 input B. TTL-compatible logic input; VIH >= 2 V, VIL <= 0.8 V at VCC = 4.5-5.5 V.
3 1Y output Gate 1 output (Y = 1A + 1B). Push-pull CMOS output, drives ±4 mA at 5 V; VOH >= 4.4 V @ IOH = -4 mA, VOL <= 0.33 V @ IOL = 4 mA.
4 2A input Gate 2 input A. TTL-compatible logic input.
5 2B input Gate 2 input B. TTL-compatible logic input.
6 2Y output Gate 2 output (Y = 2A + 2B). Push-pull CMOS output.
7 GND power_in Ground reference (0 V). Must be connected to system ground.
8 3Y output Gate 3 output (Y = 3A + 3B). Push-pull CMOS output.
9 3A input Gate 3 input A. TTL-compatible logic input.
10 3B input Gate 3 input B. TTL-compatible logic input.
11 4Y output Gate 4 output (Y = 4A + 4B). Push-pull CMOS output.
12 4A input Gate 4 input A. TTL-compatible logic input.
13 4B input Gate 4 input B. TTL-compatible logic input.
14 VCC power_in Positive supply voltage. Operating range 4.5 V to 5.5 V (absolute max 7 V). Decouple with 0.1 µF ceramic near the pin.
