Working Principles

The 74LV373PW,118 is an octal D-type transparent latch. It stores data from the input pins (D0-D7) and transfers it to the output pins (Q0-Q7) when the clock pulse (CP) rises. The latch can be enabled or disabled using the output enable (OE) pin. When the OE pin is high, the outputs are in a high-impedance state, allowing other devices to drive the bus. The latch operates within a specified voltage range and provides reliable data storage and transfer in digital systems.
