Working Principles

The MC74LCX373DTG operates as an octal transparent latch, meaning that the input data is directly transferred to the outputs when the latch enable (LE) signal is active. The output enable (OE) signal controls the state of the outputs, allowing them to be either active or in a high-impedance state.

When the LE signal is inactive, the latch holds the previously stored data, ensuring data integrity. The CLK input is used to synchronize the data transfer process.
