Working Principles

SN74HCT373N operates as an octal transparent latch with 3-state outputs. The latch enable (LE) input controls the storage of data from the data inputs (D0-D7). When LE is high, the latch is enabled, allowing the data to be stored. The output enable (OE) input determines whether the stored data is available at the outputs (Q0-Q7). When OE is low, the outputs are active, and when it is high, the outputs are in a high-impedance state.
