SN74HC4040N 12-bit asynchronous binary counter, 2 ... 6 V, DIP-16

12-Bit Asynchronous Binary Counters

Description 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.

Features - 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 - ±4-mA Output Drive at 5 V - Low Input Current of 1 µA Max
