Working Principles

The 74LVTH373MTC is a transparent latch that can store and transfer 8 bits of data. It operates by latching the input data when the latch enable (LE) signal is high and transferring the latched data to the output when the clock pulse (CP) signal transitions from low to high. The output enable (OE) pin controls the output state, allowing the user to disable or enable the outputs as needed.
