Working Principles

The 74LVCH162373APVG operates based on the principles of digital logic. When the latch enable (LE) input is high, the IC acts as a transparent latch, allowing data to pass through from the input to the output. When LE is low, the IC latches the data, holding it at the output until the next transition.

The bidirectional data flow is achieved by using a combination of multiplexers and tristate buffers. The output enable (OE) input controls the tristate buffers, enabling or disabling the outputs as needed.
