Working Principles

The SN74LV374ATPWT operates as an octal D-type transparent latch with 3-state outputs. It stores data on its inputs and transfers it to the outputs when the latch enable (LE) signal is active. The outputs can be enabled or disabled using the output enable (OE) signal. When the OE signal is active, the outputs are in a high-impedance state, allowing other devices to drive the bus. The latch operates on a clock signal (CLK), which controls the timing of data storage and transfer.
