• Limited output capability may restrict use in certain high-current applications.
• Propagation delay of 14 ns (max) may impact timing-sensitive operations.

Working Principles

The M74HCT573TTR functions as a latch by storing and transferring data within digital systems. When the latch enable (LE) signal is high, the IC captures the data present at its inputs (D0-D7) and holds it until the next positive clock edge. The output enable (OE) signal determines whether the stored data is accessible at the outputs (Q0-Q7). This IC operates with a wide range of supply voltages, making it compatible with various digital systems.
