SN74HC4040 (ACTIVE) 12-Bit Asynchronous Binary Counters

12-Bit Asynchronous Binary Counters - SN74HC4040
Datasheet
 

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
