SN74LV573ATNSR

Latches Overview

The SN74LV573ATNSR is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the LV logic series. It features eight non-inverting outputs with three-state capability and operates within a supply voltage range of 2 V to 5.5 V. 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 low-level output currents of 32 mA and high-level output currents of -16 mA, with a static current of 20 uA. Designed for surface-mount applications, it is housed in a TSSOP-20 package and functions reliably across an operating temperature range from -40 C to +85 C.

Latches Feature Summary

• Octal transparent D-type latch architecture with tri-state outputs
• Wide supply voltage compatibility ranging from 2 V to 5.5 V
• High drive capability supporting 32 mA low-level and -16 mA high-level output currents

Latches Applications

• Parallel-to-serial data conversion circuits
• Buffering and register applications in digital systems
• I/O port expansion for microcontrollers

Latches Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when sourcing. Confirm the TSSOP-20 package type matches your PCB footprint requirements. Ensure the LV series voltage range aligns with your system's power rails. Check RoHS compliance status through official manufacturer documentation before finalizing procurement decisions.

Latches Selection Notes

Select this component for designs requiring wide voltage operation between 2 V and 5.5 V. The LV series offers lower power consumption compared to standard CMOS families while maintaining adequate drive strength. Consider the TSSOP-20 package for space-constrained surface-mount layouts. Verify that the propagation delay characteristics meet your timing constraints at the intended operating voltage.

Latches Part Context

This part belongs to the SN74LV573A family of octal latches. It shares functional similarities with other variants like SN74LV573ADBR and SN74LV573ADWR but differs in package style. The LV series is designed for low-voltage applications, distinguishing it from higher-voltage counterparts in the broader logic IC portfolio.

Latches Replacement Considerations

SN74LV573ADBR (SSOP-20) and SN74LV573ADWR (SOIC-20) are pin-compatible alternatives within the same logical family. Verify package dimensions and thermal characteristics when substituting.
