Working Principles

The 54FCT373ATLB operates as an octal transparent latch, meaning that it can store and transfer data between its inputs (D0-D7) and outputs (Q0-Q7). The latch is controlled by the latch enable (LE) input, which determines whether the latch is transparent or latched.

When the LE input is high, the latch is transparent, allowing the data on the inputs to pass through to the outputs. When the LE input is low, the latch is latched, holding the last data inputted until the LE input goes high again.

The output enable (OE) input controls the state of the outputs. When OE is high, the outputs are in a high-impedance state, effectively disconnecting them from the rest of the circuit. When OE is low, the outputs reflect the data stored in the latch.
