Product Summary

The SN74HC4040DR is a 12-stage asynchronous binary counter, 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 of SN74HC4040DR is advanced on a high-to-low transition at the clock (CLK) input. Applications of SN74HC4040DR include time-delay circuits, counter controls, and frequency-dividing circuits.

Parametrics
