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. Applications include time-delay circuits, counter controls, and freq.
• 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
