SN74HCS32PWR from Texas Instruments, in a TSSOP-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	Channel 1, Input A. Schmitt-trigger CMOS input to gate 1 (Y = A + B).
2	1B	input	Channel 1, Input B. Schmitt-trigger CMOS input to gate 1 (Y = A + B).
3	1Y	output	Channel 1, Output Y. CMOS push-pull OR-gate output (1A + 1B). Drive capability ±7.8 mA at Vcc = 6 V.
4	2A	input	Channel 2, Input A. Schmitt-trigger CMOS input to gate 2.
5	2B	input	Channel 2, Input B. Schmitt-trigger CMOS input to gate 2.
6	2Y	output	Channel 2, Output Y. CMOS push-pull OR-gate output (2A + 2B).
7	GND	power_in	Ground reference (0 V). Connect to system ground.
8	3Y	output	Channel 3, Output Y. CMOS push-pull OR-gate output (3A + 3B).
9	3A	input	Channel 3, Input A. Schmitt-trigger CMOS input to gate 3.
10	3B	input	Channel 3, Input B. Schmitt-trigger CMOS input to gate 3.
