Pinout

Pin	Name	Type	Function
1	1A	input	Gate 1, Schmitt trigger input A. CMOS logic input with hysteresis; unused inputs must be tied to VDD, VSS, or another input.
2	1B	input	Gate 1, Schmitt trigger input B. CMOS logic input with hysteresis; unused inputs must be tied to VDD, VSS, or another input.
3	1Y	output	Gate 1 NAND output. Push-pull CMOS output; Y = NOT(A AND B).
4	2Y	output	Gate 2 NAND output. Push-pull CMOS output; Y = NOT(A AND B).
5	2A	input	Gate 2, Schmitt trigger input A. CMOS logic input with hysteresis; unused inputs must be tied to VDD, VSS, or another input.
6	2B	input	Gate 2, Schmitt trigger input B. CMOS logic input with hysteresis; unused inputs must be tied to VDD, VSS, or another input.
7	VSS	power_in	Ground reference, 0 V. Negative supply rail for the device.
8	3A	input	Gate 3, Schmitt trigger input A. CMOS logic input with hysteresis; unused inputs must be tied to VDD, VSS, or another input.
9	3B	input	Gate 3, Schmitt trigger input B. CMOS logic input with hysteresis; unused inputs must be tied to VDD, VSS, or another input.
10	3Y	output	Gate 3 NAND output. Push-pull CMOS output; Y = NOT(A AND B).
11	4Y	output	Gate 4 NAND output. Push-pull CMOS output; Y = NOT(A AND B).
12	4A	input	Gate 4, Schmitt trigger input A. CMOS logic input with hysteresis; unused inputs must be tied to VDD, VSS, or another input.
13	4B	input	Gate 4, Schmitt trigger input B. CMOS logic input with hysteresis; unused inputs must be tied to VDD, VSS, or another input.
14	VDD	power_in	Positive supply voltage. Recommended operating range 3 V to 15 V; absolute max 18 V referenced to VSS.
