Working Principles

The PI74FCT373ATS is an octal transparent latch that stores and transfers data. It operates by latching the input data when the latch enable (G) signal is high. The stored data can be outputted through the 3-state outputs (Q0-Q7) when the output enable (OE) signal is also high. The gates enable (G) pin controls the latching function, while the output enable (OE) pin controls the output state.
