description
The ’LV4040A devices are 12-bit 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.
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.
