SN74LVC573ADWRG4

Latches Overview

The SN74LVC573ADWRG4 is an octal transparent D-type latch with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage of 1.65 V to 3.6 V and accepts input voltages up to 5.5 V. The device features a maximum propagation delay of 6.9 ns at 3.3 V and typical output ground bounce of 2 V at VCC = 3.3 V. It provides high drive current, supporting up to 24 mA low-level and -24 mA high-level output currents. The component is housed in a 20-pin SOIC package and supports mixed-mode signal operation.

Latches Feature Summary

• Supports mixed-mode signal operation allowing 5-V input/output voltage compatibility with 3.3-V VCC
• Includes Ioff circuitry for live insertion, partial power-down mode, and back drive protection
• Features 3-state outputs designed for driving highly capacitive or relatively low-impedance loads

Latches Applications

• Servers
• PC and notebook computers
• Network switches
• Health and fitness wearables

Latches Procurement Notes

Verify the specific ordering suffix G4 indicates compliance with RoHS standards and lead finish specifications. Confirm the package type matches the required SOIC-20 footprint and thermal characteristics. Ensure the operating temperature range aligns with system requirements, as this variant supports industrial temperatures. Cross-reference the datasheet revision date to confirm parameter validity.

Latches Selection Notes

Select this component when designing systems requiring octal data latching with high-speed performance under low-voltage conditions. The LVC series offers superior speed compared to HC logic while maintaining CMOS power efficiency. Consider the 5.5-V tolerant inputs if interfacing with legacy 5-V logic sources without level shifters. Evaluate the 3-state capability for bus-oriented architectures where multiple devices share data lines.

Latches Part Context

This part belongs to the SNx4LVC573A family of octal transparent D-type latches. It shares functional similarities with the SN54LVC573A but differs in operating voltage ranges and temperature ratings. The device is part of Texas Instruments' broader LVC logic portfolio, which focuses on low-voltage applications ranging from 1.65 V to 3.6 V.
