MC74HC132ADR2G 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 Schmitt-trigger input A. Positive-going threshold VT+ typ 2.9 V and negative-going threshold VT- typ 1.9 V at VCC=4.5 V; input leakage 1.0 uA max.
2	B1	input	Gate 1 Schmitt-trigger input B. Schmitt-trigger CMOS input, hysteresis typ 0.9 V at VCC=4.5 V; compatible with CMOS/NMOS/LSTTL outputs (with pull-up for LSTTL).
3	Y1	output	Gate 1 NAND output, Y1 = NOT(A1 AND B1). Push-pull CMOS output, drives 10 LSTTL loads; IOUT up to 4.0 mA at VCC=4.5 V with VOH >= 3.98 V and VOL <= 0.26 V.
4	A2	input	Gate 2 Schmitt-trigger input A. Same Schmitt-trigger characteristics as A1; must not be left floating (tie to VCC or GND if unused).
5	B2	input	Gate 2 Schmitt-trigger input B. Schmitt-trigger CMOS input, hysteresis typ 0.9 V at VCC=4.5 V.
6	Y2	output	Gate 2 NAND output, Y2 = NOT(A2 AND B2). Propagation delay tPD typ ~25 ns at VCC=4.5 V, CL=50 pF.
7	GND	power_in	Ground / 0 V reference for the device. Maximum DC ground current 75 mA per pin.
8	Y3	output	Gate 3 NAND output, Y3 = NOT(A3 AND B3). CMOS push-pull output.
9	A3	input	Gate 3 Schmitt-trigger input A. Schmitt-trigger CMOS input.
10	B3	input	Gate 3 Schmitt-trigger input B. Schmitt-trigger CMOS input.
11	Y4	output	Gate 4 NAND output, Y4 = NOT(A4 AND B4). CMOS push-pull output; drives 10 LSTTL loads.
12	A4	input	Gate 4 Schmitt-trigger input A. Schmitt-trigger CMOS input.
13	B4	input	Gate 4 Schmitt-trigger input B. Schmitt-trigger CMOS input.
14	VCC	power_in	Positive supply, 2.0 to 6.0 V recommended (absolute max 7.0 V). Quiescent supply current ICC typ 1.0 uA at 25 degC.
