SN74LV573AZQNR

Latches Overview

The SN74LV573AZQNR is an octal transparent D-type latch featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and supports a wide operating temperature range from -40°C to +85°C. The device utilizes a 20-BGA MICROSTAR JUNIOR package. Key electrical characteristics include 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 exhibits a static current of 20 uA, with low-level output current capability of 32 mA and high-level output current of -16 mA.

Latches Feature Summary

• Octal transparent D-type latch architecture with eight independent data paths
• Three-state output capability for bus-oriented systems
• Wide supply voltage operation supporting 2 V to 5.5 V ranges
• Industrial temperature rating spanning -40°C to +85°C

Latches Applications

• Bus-oriented memory mapping
• Clock buffering
• Buffered registers

Latches Procurement Notes

Verify the specific package type and pinout configuration against the official datasheet before integration. Confirm that the 20-BGA MICROSTAR JUNIOR footprint matches the PCB design requirements. Ensure voltage levels and signal integrity meet the specified propagation delay constraints for the target application speed.

Latches Selection Notes

Select this component when an octal latch with three-state outputs is required in a compact BGA package. It is suitable for applications needing wide voltage compatibility and industrial temperature resilience. Consider the package size and thermal characteristics relative to other available logic families.

Latches Part Context

This part belongs to the SN74LV573A series of octal D-type latches. It shares functional similarities with other members of the LV family but differs in packaging and specific electrical parameters. The AZQNR suffix indicates the 20-BGA MICROSTAR JUNIOR package variant.

Latches Replacement Considerations

Direct substitutes may include other SN74LV573 variants with different packages, such as SN74LV573APWR or SN74LV573ATDWR, provided the package form factor is adaptable.
