SN74LV573ATNS

Latches Overview

The SN74LV573ATNS is an octal transparent D-type latch manufactured by Texas Instruments. It features eight D-type latches with three-state outputs, designed for low-voltage CMOS applications. The device operates within a supply voltage range of 2 V to 5.5 V. Propagation delay specifications are 18.7 ns at 2.5 V, 14.5 ns at 3.3 V, and 8.8 ns at 5 V. Static current consumption is typically 20 uA. The component supports low-level output currents of 32 mA and high-level output currents of -16 mA. It functions in non-inverting polarity and is housed in a 20-pin SOIC package.

Latches Feature Summary

• Octal configuration providing eight independent transparent D-type latches
• Three-state outputs enabling direct bus-driven connections
• Wide operating voltage compatibility from 2 V to 5.5 V

Latches Applications

• Buffer registers
• I/O port circuits
• Bus-oriented architectures

Latches Procurement Notes

Verify the specific suffix 'ATNS' against the manufacturer's official datasheet to confirm pinout, package dimensions, and electrical characteristics match your design requirements. Ensure the ordering code aligns with the desired tape-and-reel quantity and RoHS compliance status as defined in the latest TI documentation.

Latches Selection Notes

Select this component when designing systems requiring multiple data storage elements with tri-state control under varying voltage conditions. The LV series offers lower power consumption compared to standard logic families while maintaining sufficient drive capability for most digital interfaces.

Latches Part Context

This part belongs to the SN74LV573A family of octal transparent D-type latches. Variants such as SN74LV573ADWR and SN74LV573APWR share similar logical functionality but differ in packaging styles like SOIC or TSSOP. The SN74LVTH573 represents a related 3.3-V ABT family with different speed and voltage characteristics.

Latches Replacement Considerations

SN74LV573ADWR and SN74LV573APWR are functionally equivalent alternatives within the same family, differing primarily in package type.
