74FCT573ATSOG

Latches Overview

The IDT74FCT573ATSOG is an octal transparent D-type latch belonging to the 74FCT logic series. It features TTL-compatible input and output levels, supporting a supply voltage range of 4.75 V to 5.25 V. The device provides three-state outputs with a typical propagation delay of 5.2 ns at 5 V. Designed for industrial applications, it operates within a temperature range of -40 °C to +85 °C and is housed in a 20-pin SOIC package.

Latches Feature Summary

• Octal transparent latch architecture providing eight independent data storage channels
• TTL-compatible input and output interface levels for system integration
• Three-state output capability enabling bus-driven configurations

Latches Applications

• Memory address latching in computing systems
• I/O port buffering and control
• Bus driver implementations requiring temporary data storage

Latches Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status and check for End-of-Life notices, as this part may be discontinued by Renesas Electronics. Ensure the specific suffix matches required packaging and lead-free specifications before ordering.

Latches Selection Notes

Select this component when an octal latch with TTL compatibility and three-state outputs is required. Verify that the 4.75 V to 5.25 V operating voltage aligns with the target system power rails. Consider the 5.2 ns propagation delay and industrial temperature range suitability for the intended application environment.

Latches Part Context

This component is part of the broader 74FCT family of high-speed CMOS logic devices. Originally manufactured by IDT, production rights have transitioned to Renesas Electronics. The 74FCT573 variant specifically serves as a direct replacement for older ABT functions, offering improved speed and lower power consumption while maintaining pin compatibility.

Latches Replacement Considerations

Public confirmed substitute part numbers include CY74FCT573ATSOC from Texas Instruments.
