CY74FCT573ATQC

Latches Overview

The CY74FCT573ATQC is an octal D-type transparent latch manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and features three-state outputs. The device is housed in a 20-pin SSOP package with a width of 3.90 mm. It supports a wide operating temperature range from -40°C to +85°C. Key electrical characteristics include a propagation delay of 2 ns, high-level output current of 32 mA, and low-level output current of 64 mA. The logic series is designated as 74FCT.

Latches Feature Summary

• Octal D-type transparent latch configuration
• Three-state output capability
• Wide operating temperature range support

Latches Applications

• Data storage applications
• Bus-oriented systems

Latches Procurement Notes

Verify the exact suffix against official documentation, as 'ATQC' may denote specific tape-and-reel packaging or temperature grades distinct from standard tubes. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Ensure compatibility with existing PCB footprints for the 20-SSOP package. Cross-reference with the manufacturer's latest datasheet to validate pinout and electrical specifications.

Latches Selection Notes

Select this component for designs requiring octal data latching with high drive strength. The 74FCT series offers faster switching speeds compared to standard CMOS counterparts. Consider the 20-SSOP package constraints for board space. Verify input logic levels match the system TTL requirements. Evaluate power consumption needs against the specified operating current.

Latches Part Context

This part belongs to the Texas Instruments 74FCT logic family, which combines the speed of bipolar technology with CMOS power efficiency. The 74FCT573 specifically provides eight D-type latches with transparent operation when enabled. It is designed for high-performance digital systems requiring reliable data retention and fast propagation delays.

Latches Replacement Considerations

Check for direct equivalents such as the CY74FCT573TQCT or other 74FCT573 variants from Texas Instruments. Ensure pin compatibility and electrical parameters match before substitution. Verify that any alternative package types fit the mechanical constraints of the design.
