74LCX573WM

Latches Overview

The onsemi 74LCX573WM is an octal transparent D-type latch featuring three-state outputs, manufactured in the LCX logic family. It operates within a supply voltage range of 2V to 3.6V and utilizes a 20-SOIC surface-mount package. The device provides high-speed performance with a propagation delay of 1.5ns and supports output drive currents of 24mA for both high and low states. Designed for robust operation, it functions across an extended temperature range from -55°C to 125°C and complies with RoHS3 standards.

Latches Feature Summary

• Octal transparent D-type latch architecture with eight independent data paths
• Three-state outputs enabling direct bus line driving and system interfacing
• Low power consumption characteristics inherent to the LCX logic family
• Extended industrial temperature rating for reliable environmental operation

Latches Applications

• Data register storage in digital processing systems
• Bus-oriented memory mapping applications
• Clock domain crossing synchronization circuits
• Portable equipment requiring low voltage operation

Latches Procurement Notes

Verify component authenticity through authorized distribution channels due to potential availability of refurbished or counterfeit units. Confirm package marking consistency with official datasheet specifications. Ensure compliance with current environmental directives such as RoHS3 before integration into final assemblies. Validate supplier documentation against original manufacturer records to guarantee traceability and quality assurance throughout the supply chain.

Latches Selection Notes

Select this component when designing systems requiring octal latching with three-state control under low voltage conditions. The LCX series offers superior speed compared to standard HC logic while maintaining lower power dissipation. Consider the 20-SOIC package dimensions for PCB layout constraints. Verify that the operating voltage range aligns with the system's power supply rails and that the temperature rating meets the application's environmental requirements.

Latches Part Context

This part belongs to the 74LCX logic family, which represents low-voltage CMOS technology optimized for high-speed performance. The 74LCX573 variant specifically implements octal D-latch functionality with tri-state outputs. It serves as a complementary solution to other 74-series logic families, offering improved switching speeds and reduced power consumption suitable for modern portable and battery-operated electronic devices.

Latches Replacement Considerations

Direct substitutes include MC74LCX573DWG and MC74LCX573DWR2G from onsemi. Cross-manufacturer equivalents such as SN74LVC573ADWR from Texas Instruments may require verification of voltage compatibility and pin configuration alignment.
