12-bit asynchronous binary counters.
* Wide operating voltage range of 2 V to 6 V
* Outputs can drive up to 10 LSTTL loads
* Low power consumption, 80-µA max ICC
* Typical tpd = 12 ns
* ±.
include time-delay circuits, counter controls, and frequency-dividing circuits.

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-t.
