Working Principles

The MC74LVX373DWR2 operates as an octal transparent latch. When the latch enable input (LE) is high, the data on the D0-D7 inputs is transferred to the Q0-Q7 outputs. The latch remains transparent as long as LE is high. When LE is low, the outputs are latched and hold their values until the next transition of LE from low to high.

The individual output enable inputs (OE1) control the 3-state outputs. When OE1 is low, the outputs are active and reflect the data stored in the latch. When OE1 is high, the outputs are in a high-impedance state, allowing other devices to drive the bus.
