description/ordering information
NC − No internal connection
The ’HC4040 devices are 12-stage asynchronous binary counters, with the outputs of all stages available
externally. A high level at the clear (CLR) input asynchronously clears the counter and resets all outputs low.
The count is advanced on a high-to-low transition at the clock (CLK) input. Applications include time-delay
circuits, counter controls, and frequency-dividing circuits.
