Working Principles

The 74HCT373DB,118 operates as an octal D-type transparent latch. When the latch enable (LE) input is high, the data inputs (D0-D7) are transferred to the outputs (Q0-Q7). The latch remains transparent as long as LE is high, allowing continuous data flow. When the output enable (OE) input is low, the outputs are enabled and can drive external circuitry. When OE is high, the outputs are in a high-impedance state.
