TEXAS INSTRUMENTS  SN74LV4040AD  逻辑芯片, 异步二进制计数器, 16SOIC

The is a 12-bit Asynchronous Binary Counter 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 input. Applications include time-delay circuits, counter controls and frequency-dividing circuits. It is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down.
