SN74AHC86DR 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	Channel 1, Input A. CMOS logic input to gate 1; high-impedance input, VIH >= 0.7VCC / VIL <= 0.3VCC over the 2-5.5 V VCC range.
2	1B	input	Channel 1, Input B. CMOS logic input to gate 1; input leakage +/-1 uA max, Ci ~ 4-10 pF.
3	1Y	output	Channel 1, Output Y = 1A XOR 1B. Totem-pole CMOS output rated IOH/IOL = +/-8 mA at VCC = 5 V +/-0.5 V (+/-4 mA at 3.3 V +/-0.3 V).
4	2A	input	Channel 2, Input A. CMOS logic input to gate 2.
5	2B	input	Channel 2, Input B. CMOS logic input to gate 2.
6	2Y	output	Channel 2, Output Y = 2A XOR 2B. Totem-pole CMOS output, +/-8 mA drive at 5 V.
7	GND	power_in	Device ground (0 V) reference for all four XOR gates.
8	3Y	output	Channel 3, Output Y = 3A XOR 3B. Totem-pole CMOS output, +/-8 mA drive at 5 V.
9	3A	input	Channel 3, Input A. CMOS logic input to gate 3.
10	3B	input	Channel 3, Input B. CMOS logic input to gate 3.
11	4Y	output	Channel 4, Output Y = 4A XOR 4B. Totem-pole CMOS output, +/-8 mA drive at 5 V.
12	4A	input	Channel 4, Input A. CMOS logic input to gate 4.
13	4B	input	Channel 4, Input B. CMOS logic input to gate 4.
14	VCC	power_in	Positive supply, 2 V to 5.5 V recommended (absolute max 7 V). ICC quiescent current is 20 uA max at 5.5 V. Bypass with 0.1 uF ceramic close to the pin.
