3 1QA output Counter 1 A Output, LSB of 4-bit binary counter
4 1QB output Counter 1 B Output of 4-bit binary counter
5 1QC output Counter 1 C Output of 4-bit binary counter
6 1QD output Counter 1 D Output, MSB of 4-bit binary counter
7 GND power_in Ground
8 2QD output Counter 2 D Output, MSB of 4-bit binary counter
9 2QC output Counter 2 C Output of 4-bit binary counter
10 2QB output Counter 2 B Output of 4-bit binary counter
11 2QA output Counter 2 A Output, LSB of 4-bit binary counter
12 2CLR input Counter 2 Clear Input, active high to reset all counter 2 outputs to low
13 2CLK/ input Counter 2 Clock Input, triggers advance on negative-going transition when 2CLR is low
14 VCC power_in Supply voltage, 2V to 5.5V recommended operating range
