MC74HC86ADR2G from onsemi, 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	A1	input	Gate 1 input A. CMOS logic input (V_IH >= 0.7V_CC typ, V_IL <= 0.2V_CC typ). Input leakage <= 1 uA.
2	B1	input	Gate 1 input B. CMOS logic input; XOR'd with A1 to produce Y1.
3	Y1	output	Gate 1 output = A1 XOR B1. Push-pull CMOS output; drive capability 10 LSTTL loads.
4	A2	input	Gate 2 input A. CMOS logic input.
5	B2	input	Gate 2 input B. CMOS logic input; XOR'd with A2 to produce Y2.
6	Y2	output	Gate 2 output = A2 XOR B2. Push-pull CMOS output.
7	GND	power_in	Ground reference (0 V). Common return for V_CC supply and all logic signals.
8	Y3	output	Gate 3 output = A3 XOR B3. Push-pull CMOS output.
9	A3	input	Gate 3 input A. CMOS logic input.
10	B3	input	Gate 3 input B. CMOS logic input; XOR'd with A3 to produce Y3.
11	Y4	output	Gate 4 output = A4 XOR B4. Push-pull CMOS output.
12	A4	input	Gate 4 input A. CMOS logic input.
13	B4	input	Gate 4 input B. CMOS logic input; XOR'd with A4 to produce Y4.
14	VCC	power_in	Positive supply, 2.0 V to 6.0 V (referenced to GND). Bypass with a 0.1 uF ceramic close to the pin. Absolute max 7.0 V.
