CD74FCT573M

Latches Overview

The CD74FCT573M is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the FCT logic series. It features eight independent D-type latches with three-state outputs in a 20-pin SOIC package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a propagation delay of 6.8 ns at 5 V. It provides a low-level output current of 32 mA and a high-level output current of -15 mA, with a static current consumption of 8 uA. The component functions across a temperature range from 0°C to +70°C.

Latches Feature Summary
