Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CLOCK A | input | Clock input for counter A; counter increments on positive-going edge when ENABLE A is high, or on negative-going edge when ENABLE A is held high and clock drives the increment. |
| 2 | ENABLE A | input | Enable input for counter A; counter advances on positive-going CLOCK transition when ENABLE is high; hold high for single-unit clocked operation. |
| 3 | Q1A | output | BCD up-counter A stage-1 (LSB) output; VOL ≤ 50 mV, VOH ≥ 4.95 V at VDD = 5 V no load. |
| 4 | Q2A | output | BCD up-counter A stage-2 output; VOL ≤ 50 mV, VOH ≥ 4.95 V at VDD = 5 V no load. |
| 5 | Q3A | output | BCD up-counter A stage-3 output; VOL ≤ 50 mV, VOH ≥ 4.95 V at VDD = 5 V no load. |
| 6 | Q4A | output | BCD up-counter A stage-4 (MSB) output; connect to ENABLE B for ripple cascading while CLOCK B is held low. |
| 7 | RESET A | input | Active-high asynchronous reset for counter A; a high level forces Q1A-Q4A to logic 0; minimum reset pulse width 250 ns at VDD = 5 V. |
| 8 | VSS | power_in | Ground reference (0 V); all voltages referenced to this terminal. |
| 9 | CLOCK B | input | Clock input for counter B; counter increments on positive-going edge when ENABLE B is high; hold low for ripple cascading from Q4A. |
| 10 | ENABLE B | input | Enable input for counter B; counter advances on positive-going CLOCK B transition when high; used as ripple-cascade input driven by Q4A. |
| 11 | Q1B | output | BCD up-counter B stage-1 (LSB) output; VOL ≤ 50 mV, VOH ≥ 4.95 V at VDD = 5 V no load. |
| 12 | Q2B | output | BCD up-counter B stage-2 output; VOL ≤ 50 mV, VOH ≥ 4.95 V at VDD = 5 V no load. |
| 13 | Q3B | output | BCD up-counter B stage-3 output; VOL ≤ 50 mV, VOH ≥ 4.95 V at VDD = 5 V no load. |
| 14 | Q4B | output | BCD up-counter B stage-4 (MSB) output; connect to ENABLE of subsequent counter for ripple cascading. |
| 15 | RESET B | input | Active-high asynchronous reset for counter B; a high level forces Q1B-Q4B to logic 0; minimum reset pulse width 250 ns at VDD = 5 V. |
| 16 | VDD | power_in | Positive supply voltage; operating range -0.5 V to +20 V (absolute maximum); parametric ratings at 5 V, 10 V and 15 V. |
