CY74FCT2573CTQCT

Latches Overview

The CY74FCT2573CTQCT is an octal D-type transparent latch manufactured by Texas Instruments, belonging to the FCT logic series. It features eight independent circuits with non-inverting polarity and operates within a supply voltage range of 4.75 V to 5.25 V. The device provides a propagation delay of 4.7 ns at 5 V, with low-level output current capability of 32 mA and high-level output current of -15 mA. Designed for surface mount applications, it is housed in a QSOP-20 package and functions reliably across an operating temperature range from -40°C to +85°C.

Latches Feature Summary
