CD74FCT573E

Latches Overview

The CD74FCT573E is an octal transparent D-type latch with three-state outputs manufactured by Texas Instruments. It belongs to the FCT logic series and operates within a supply voltage range of 4.75 V to 5.25 V. The device features eight bits of storage capacity in a 20-pin SOIC package. Key electrical characteristics include a propagation delay of 6 ns at 5 V, low static current of 8 uA, and output drive capabilities of -15 mA high level and 64 mA low level. It supports a wide operating temperature range from 0°C to +70°C.

Latches Feature Summary

• Provides octal data storage via transparent D-type latching mechanism
• Integrates three-state outputs for efficient bus-driven applications
• Utilizes BiCMOS technology for high-speed performance and low power consumption

Latches Applications

• General-purpose parallel data storage
• Bus-oriented memory mapping
• Register files in digital systems

Latches Procurement Notes

Verify the specific suffix 'E' indicates the SOIC-20 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the supply voltage matches the 4.75 V to 5.25 V requirement for proper operation. Check for automotive qualification if required, as standard versions may not meet AEC-Q100 standards.

Latches Selection Notes

Select this component for designs requiring fast octal latching with bus isolation. Compare against HC/HCT series for speed advantages and FCT series variants for package options. Consider the 6 ns propagation delay for timing-critical paths. Evaluate thermal performance within the 0°C to +70°C industrial range. Verify pin compatibility with existing PCB layouts using the SOIC-20 footprint.

Latches Part Context

This part is part of Texas Instruments' FCT (Fast CMOS Technology) family, designed for high-speed digital applications. It complements other FCT devices like the CD74FCT541 buffer. The series emphasizes low power dissipation while maintaining high switching speeds suitable for modern digital logic systems.

Latches Replacement Considerations

Direct substitutes include other CD74FCT573 variants with different package suffixes such as M (SOIC) or N (PDIP). Cross-reference with SN74FCT573 for equivalent functionality. Verify pinout and electrical specifications match before substitution.
