SN74LVC573ANSR

Latches Overview

The SN74LVC573ANSR 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 provides high drive current capability, supporting loads up to 24 mA. It includes Ioff circuitry for partial-power-down support and live insertion protection. The component is housed in a 20-pin SOIC package.

Latches Feature Summary

• Supports mixed-mode signal operation on all ports, allowing 5-V input/output voltage compatibility with a 3.3-V VCC supply.
• Includes Ioff circuitry that disables outputs to prevent damaging current backflow when the device is powered down.
• Features 3-state outputs designed specifically 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 'ANSR' corresponds to the SOP (NS) package variant with tape-and-reel packaging. Confirm the operating temperature range matches system requirements, as this suffix typically indicates a -40°C to 85°C rating. Ensure the datasheet revision aligns with the design specifications before finalizing procurement.

Latches Selection Notes

Select this component for applications requiring data retention in bus interface designs where high-speed performance is necessary. The 5.5-V tolerant inputs facilitate voltage translation between different logic domains. Consider the 24 mA drive strength for driving multiple outputs or heavy capacitive loads without external buffering components.

Latches Part Context

This part belongs to the SNx4LVC573A family of octal transparent D-type latches. The LVC series utilizes CMOS technology optimized for low-voltage operation while maintaining robust drive capabilities. The SN74 variant is distinguished from the SN54 series by its commercial-grade temperature range and lower minimum supply voltage threshold.
