SN74LV573AGQNR

Latches Overview

The SN74LV573AGQNR is an octal transparent D-type latch with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and supports propagation delays of 18.7 ns at 2.5 V, 14.5 ns at 3.3 V, and 8.8 ns at 5 V. The device features a static current of 20 uA, low-level output current of 32 mA, and high-level output current of -16 mA. It functions reliably across an operating temperature range from -40°C to +85°C and is housed in a 20-pin Microstar Junior (4x3) BGA package.

Latches Feature Summary

• Octal configuration providing eight independent D-type latches with tri-state control for efficient bus interfacing.
• Wide supply voltage compatibility supporting operation from 2 V to 5.5 V for diverse logic system integration.
• High-speed performance with optimized propagation delays suitable for demanding digital data handling applications.

Latches Applications

• Parallel-to-serial data conversion circuits
• Buffer registers in microprocessor systems
• I/O port expansion modules

Latches Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest documentation to ensure authenticity. Confirm that the 20-VFBGA footprint matches your PCB design constraints. Check for RoHS compliance status as indicated in the official datasheet before finalizing procurement orders.

Latches Selection Notes

Select this component when an octal latch with tri-state outputs is required in a compact surface-mount form factor. Ensure the design accommodates the 20-VFBGA package dimensions and thermal requirements. Verify that the 2 V to 5.5 V operating range aligns with the target system power rails and signal levels.

Latches Part Context

This part belongs to the SN74LV573A series of octal transparent D-type latches. It shares functional characteristics with other variants in the family but differs in packaging, specifically utilizing the 20-pin Microstar Junior BGA format instead of standard SOIC or SSOP options.

Latches Replacement Considerations

Direct pin-compatible substitutes include SN74LV573ADBR and SN74LV573ADWR, though these utilize different packages such as SSOP-20 and SOIC-20 respectively. Cross-package replacements require careful review of mechanical footprints and thermal management strategies.
