CY74FCT2573ATQCT

Latches Overview

The CY74FCT2573ATQCT is an octal D-type transparent latch manufactured by Texas Instruments within the FCT logic series. It features eight independent latches with three-state outputs, housed in a 20-pin SSOP package. The device operates at a supply voltage range of 4.75 V to 5.25 V and supports TTL input levels. Key electrical characteristics include a propagation delay of 4.7 ns at 5 V, a low-level output current of 32 mA, and a high-level output current of -15 mA. It functions reliably across an operating temperature range from -40°C to +85°C.

Latches Feature Summary

• Provides eight independent transparent latching channels for data storage applications
• Features three-state outputs to facilitate direct bus connections without external buffers
• Accepts TTL-compatible input signals for seamless integration with standard logic families

Latches Applications

• Parallel data buffering in digital systems
• Interface between microprocessors and peripheral devices
• Temporary data storage in memory architectures

Latches Procurement Notes

Verify the specific suffix 'A' against official documentation to confirm any distinct manufacturing or quality variations compared to the base model. Ensure the SSOP-20 package dimensions match the target PCB footprint. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

Latches Selection Notes

Select this component when an octal latch with three-state capability is required for high-speed data handling. The FCT series offers faster switching speeds compared to standard CMOS alternatives. Ensure the design accommodates the specified 4.75 V to 5.25 V power supply constraints and thermal requirements for the industrial temperature range.

Latches Part Context

This part belongs to the Texas Instruments CY74FCT2573T family of octal transparent latches. It shares functional similarities with other FCT series logic devices but is specifically optimized for high-speed parallel data transfer. The device complements other bus transceivers and registers within the same logic family for comprehensive system design.

Latches Replacement Considerations

The CY74FCT2573TSOCTE4 is a documented equivalent variant within the same product line. Verify pin compatibility and electrical parameters before substitution.
