DESCRIPTION

The U74HC4040 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.

FEATURES

* Wide Operating Voltage Range of 2V to 6V

* Low Power Consumption, 8μA Maximum ICC

* Typical tPD = 12 ns

* ±4mA Output Drive at 5V
