SN74LV573ATRGYR

Latches Overview

The SN74LV573ATRGYR is an octal transparent D-type latch with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs. The device supports partial-power-down mode via Ioff circuitry, allowing high-impedance states when power is removed. It is housed in a 20-VQFN package (3.5x4.5 mm) and is designed for surface-mount applications.

Latches Feature Summary

• Octal transparent D-type latch architecture with 3-state outputs
• TTL-voltage compatible input structure
• Ioff support enables partial-power-down operation

Latches Applications

• Data buffering in digital systems
• Memory address latching
• Parallel-to-serial conversion interfaces

Latches Procurement Notes

Verify the specific suffix 'RGYR' against the official datasheet to confirm the 20-VQFN package and tape-and-reel delivery format. Ensure the operating voltage requirements align with your system's 4.5 V to 5.5 V specification. Confirm RoHS compliance status through the manufacturer's documentation before procurement.

Latches Selection Notes

Select this component when an octal latch with 3-state outputs is required for 5 V logic systems. The VQFN package offers a compact footprint suitable for space-constrained designs. Consider the TTL-compatible inputs if interfacing with legacy logic families. Verify thermal performance requirements for the specific PCB layout.

Latches Part Context

This part belongs to the SN74LV573A family of octal transparent D-type latches. It shares functional similarities with other variants like SN74LV573APWR but differs in packaging and specific electrical characteristics defined by the RV or RGYR suffixes. It is distinct from LVTH or LVC series devices which operate at different voltage levels.

Latches Replacement Considerations

Direct replacements include SN74LV573APWR (TSSOP-20) and SN74LV573ATDWR (SOIC-20), though package differences require board redesign. Check for equivalent parts from other manufacturers offering 5 V octal latches in VQFN packages.
