SN74AHC32DR 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. Standard CMOS input to the first 2-input OR gate.
2	1B	input	Gate 1 input B. Standard CMOS input to the first 2-input OR gate.
3	1Y	output	Gate 1 output: 1Y = 1A + 1B. Balanced CMOS push-pull output, ±8 mA drive at VCC = 5 V.
4	2A	input	Gate 2 input A. Standard CMOS input to the second 2-input OR gate.
5	2B	input	Gate 2 input B. Standard CMOS input to the second 2-input OR gate.
6	2Y	output	Gate 2 output: 2Y = 2A + 2B. Balanced CMOS push-pull output, ±8 mA drive at VCC = 5 V.
7	GND	power_in	Ground reference (0 V) for the device.
8	3Y	output	Gate 3 output: 3Y = 3A + 3B. Balanced CMOS push-pull output, ±8 mA drive at VCC = 5 V.
9	3A	input	Gate 3 input A. Standard CMOS input to the third 2-input OR gate.
10	3B	input	Gate 3 input B. Standard CMOS input to the third 2-input OR gate.
11	4Y	output	Gate 4 output: 4Y = 4A + 4B. Balanced CMOS push-pull output, ±8 mA drive at VCC = 5 V.
12	4A	input	Gate 4 input A. Standard CMOS input to the fourth 2-input OR gate.
13	4B	input	Gate 4 input B. Standard CMOS input to the fourth 2-input OR gate.
14	VCC	power_in	Supply voltage, 2 V to 5.5 V recommended (7 V absolute max). Bypass with a 0.1 µF ceramic capacitor close to the pin.
