SN74LVC573DW

Latches Overview

The SN74LVC573DW is an octal transparent D-type latch manufactured by Texas Instruments within the LVC logic series. It features eight non-inverting outputs and operates on a single supply voltage ranging from 1.65 V to 3.6 V. The device provides low quiescent current of 10 uA and supports high drive capabilities with low-level output currents up to 32 mA and high-level output currents up to -24 mA. Propagation delays are specified at 7.7 ns at 2.7 V and 6.9 ns at 3.3 V. It functions reliably across an extended temperature range from -40°C to +125°C and utilizes a 20-pin SOIC package.

Latches Feature Summary

• Octal transparent D-type latch architecture providing eight independent data storage channels
• Wide operating voltage range supporting low-power portable applications
• High noise immunity and stable performance across industrial temperature extremes

Latches Applications

• Parallel-to-serial data conversion circuits
• Buffering and register operations in digital systems
• Data acquisition systems requiring temporary data storage

Latches Procurement Notes

Verify the specific suffix against official documentation, as variations may indicate different packaging or environmental compliance standards. Confirm the exact pinout and electrical characteristics match the target design requirements before integration. Ensure compatibility with the intended supply voltage and load conditions for reliable operation.

Latches Selection Notes

Select this component when an octal latch with wide voltage tolerance is required. Consider the propagation delay specifications relative to system clock speeds. Evaluate the thermal management needs given the extended operating temperature range and ensure the package style fits the available board space constraints.

Latches Part Context

This part belongs to the SN74LVC573A family of octal latches. It shares functional similarities with other devices in the LVC series but offers specific voltage and speed characteristics tailored for modern low-voltage digital designs. The DW suffix denotes the SOIC-20 package configuration.

Latches Replacement Considerations

SN74LVC573ADWR and SN74LVC573APWG4 are documented variants within the same product family offering similar functionality.
