SN74LV573APWT

Latches Overview

The SN74LV573APWT 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. The device provides propagation delays of 18.7 ns at 2.5 V, 14.5 ns at 3.3 V, and 8.8 ns at 5 V. It supports a low-level output current of 32 mA and a high-level output current of -16 mA. The component functions reliably across an operating temperature range from -40°C to +85°C.

Latches Feature Summary

• Octal transparent D-type latch architecture with three-state outputs
• Wide supply voltage compatibility ranging from 2 V to 5.5 V
• Low static current consumption for power efficiency
• High drive capability with 32 mA low-level output current

Latches Applications

• Portable battery-powered systems requiring low power consumption
• Clock-driven registers for data storage
• Bus-oriented architectures for data transmission
• Memory mapping applications in embedded systems

Latches Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration when ordering. Confirm RoHS compliance status through official manufacturer documentation or certified datasheets prior to integration. Ensure the selected package variant matches the PCB footprint requirements. Cross-reference the full part number against the latest Texas Instruments product selection guide to confirm availability and manufacturing status.

Latches Selection Notes

Select this component for designs requiring wide voltage operation between 2 V and 5.5 V. It serves as a suitable replacement for legacy HC/HCT logic families where lower power consumption is critical. Consider the propagation delay specifications relative to system clock speeds. Evaluate the SSOP-20 package constraints against available board space and thermal management needs.

Latches Part Context

This device belongs to the SN74LV573A series of octal transparent D-type latches. It shares functional similarities with other Texas Instruments logic ICs such as the SN74LVC573 and SN74HC573. The LV series specifically targets low-voltage applications while maintaining compatibility with standard digital interfaces. It is distinct from higher-speed ABT or LVTH variants in terms of power and speed characteristics.

Latches Replacement Considerations

SN74LV573ADBR offers identical functionality in an SSOP-20 package with different reel specifications. SN74LV573APWR provides the same electrical performance in a TSSOP-20 package. SN74LVC573ADW is compatible but operates within a narrower voltage range of 1.65 V to 3.6 V.
