Working Principles

The MM74HCT573MTCX operates as an octal D-type transparent latch with 3-state outputs. When the latch enable (LE) input is high, the data inputs (D0-D7) are transferred to the corresponding outputs (Q0-Q7). The output enable (OE) input controls the state of the outputs. When OE is low, the outputs are active; when OE is high, the outputs are in a high-impedance state.
