Working Principles

The 74LVC573ADTR2G operates based on the principles of flip-flops. It consists of eight individual transparent latches, each capable of storing a single bit of data. The latch enable (LE) and clock (CLK) signals control the transfer of data from the input pins (D0-D7) to the output pins (Q0-Q7). When the LE signal is active, the input data is latched and stored. On the rising edge of the CLK signal, the latched data is transferred to the output pins. The output enable (OE) signal allows for enabling or disabling the outputs.
