Working Principles

The 74LVC573AMTR latch operates based on the principles of flip-flops and logic gates. When the latch enable (LE) signal is active, data from the input pins (D0-D7) is stored in the respective flip-flops. The gated latch enable (G) pin controls the transfer of data to the output pins (Q0-Q7). The latch remains in this state until a new data input or a change in the latch enable signal occurs.
