74HC373 Octal D-Type Latch, 3-State Outputs IC (SMD Package)

A transparent latch like the 74HC373 captures whatever's present on its eight data inputs the moment its latch-enable line is active, then holds that value steady on its outputs once the enable goes low, even as the input lines keep changing. That makes it a common building block for de-multiplexing a shared, time-divided data bus out into several separate output registers, each latch grabbing its own slice of the bus at the right moment.
