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.
