| 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 |
