description

NC – No internal connection

The ’LV4040A devices are 12-bit asynchronous

binary counters with the outputs of all stages

availableexternally. 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.

The SN54LV4040A is characterized for operation over the full military temperature range of –55°C to 125°C.

The SN74LV4040A is characterized for operation from –40°C to 85°C.
