3	1B	input	Gate 1 data input B. CMOS logic input with clamp diodes.
4	2Y	output	Gate 2 data output. NOR output of inputs 2A and 2B. HIGH only when both 2A and 2B are LOW.
5	2A	input	Gate 2 data input A. CMOS logic input with clamp diodes.
6	2B	input	Gate 2 data input B. CMOS logic input with clamp diodes.
7	GND	power_in	Ground (0V) reference. All voltages referenced to this pin.
8	3A	input	Gate 3 data input A. CMOS logic input with clamp diodes.
9	3B	input	Gate 3 data input B. CMOS logic input with clamp diodes.
10	3Y	output	Gate 3 data output. NOR output of inputs 3A and 3B. HIGH only when both 3A and 3B are LOW.
11	4A	input	Gate 4 data input A. CMOS logic input with clamp diodes.
12	4B	input	Gate 4 data input B. CMOS logic input with clamp diodes.
13	4Y	output	Gate 4 data output. NOR output of inputs 4A and 4B. HIGH only when both 4A and 4B are LOW.
