Working Principles

The CD74ACT373MG4 is an octal transparent latch with 3-state outputs. It stores data on its inputs and retains it until a latch enable signal is received. When the latch enable signal is active, the stored data is transferred to the outputs. The output enable signal controls whether the outputs are active or in a high-impedance state.
