MC1420 increments a counter every time the input changes (low to high or high to low) and toggles its outputs state when a specified number is reached. The count is reset on reaching that number. Essentially this can serve as a divide-by-N for another clock. To use this IC as a clock on its own, use MC0420.
- Third line: The number of pulses to wait before toggling its output state (min. 5, max. 15)
- Clock (edge-triggered)
