TEXAS INSTRUMENTS SN74LV4040APW 逻辑芯片, 异步二进制计数器, 16TSSOP
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.
These devices are 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.
