SN74LV573APWR

Latches Overview

The SN74LV573APWR is an octal transparent D-type latch with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features low static current consumption of 20 uA. The device provides high drive capability with a low-level output current of 32 mA and a high-level output current of -16 mA. Propagation delays are specified as 18.7 ns at 2.5 V, 14.5 ns at 3.3 V, and 8.8 ns at 5 V. It functions reliably across an operating temperature range from -40 C to +85 C and is housed in a TSSOP-20 package.

Latches Feature Summary

• Octal transparent D-type latch architecture with three-state outputs

• High drive capability for bus-oriented applications
• Low static current consumption

Latches Applications

• Bus-oriented architectures
• Clock drivers
• Buffer circuits
• Register files

Latches Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-20 package and reel packaging configuration. Confirm RoHS compliance status through official documentation. Ensure the ordering part number matches the required tape and reel quantity specifications for production integration.

Latches Selection Notes

Select this component for designs requiring wide voltage compatibility between 2 V and 5.5 V. The LV series offers faster propagation speeds compared to standard HC logic while maintaining lower power consumption. Verify that the TSSOP-20 footprint aligns with the PCB layout requirements and thermal management needs.

Latches Part Context

This device belongs to the SN74LV573A family of octal latches. It shares functional similarities with other Texas Instruments parts like the SN74LV573ADBR and SN74LV573ADWR, differing primarily in package type such as SSOP-20 or SOIC-20. The LV series is designed for low-voltage CMOS applications requiring high performance.

Latches Replacement Considerations

SN74LV573ADBR (SSOP-20), SN74LV573ADWR (SOIC-20). These variants share identical electrical characteristics but differ in physical package dimensions.
