SN54HC4040J - 12-Bit Asynchronous Binary Counters

Download the SN54HC4040J datasheet PDF. This datasheet also covers the SN54HC4040 variant, as both devices belong to the same 12-bit asynchronous binary counters family and are provided as variant models within a single manufacturer datasheet.

General 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-tolow transition at the clock (CLK) input.

Key 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 2.
