These synchronous up/down decade counters are counters that make use of logic input and then changes the output when there is a state change in the clock input signal while the logic input pins have a high level logic. Up/down decade counters are very useful and common components used to save quantity data whenever needed.
Supply voltage | 4.5V ~ 5.5V |
| Min high level input voltage | 2V |
| Max low level input voltage | 0.8V |
| Supply current | 35mA |
