SN74LVTH573PW

Latches Overview

The SN74LVTH573PW is an octal transparent D-type latch manufactured by Texas Instruments, featuring 3-state outputs. It operates within a supply voltage range of 2.7 V to 3.6 V and utilizes the LVTH logic series. The device provides non-inverting data storage with a propagation delay of 2.9 ns at 3.3 V. It supports low-level output currents of 32 mA and high-level output currents of -32 mA. Packaged in a TSSOP-20 surface-mount format, it functions reliably across temperatures from -40°C to +85°C.

Latches Feature Summary

• Octal transparent D-type latch architecture with 3-state outputs for bus-driven applications
• ABT technology ensures fast switching speeds with low power consumption
• Compatible with standard CMOS logic levels for versatile interface integration

Latches Applications

• Parallel-to-serial data conversion circuits
• Buffering and register operations in digital systems
• Memory address latching in computer architectures

Latches Procurement Notes

Verify the specific package variant, as the PW suffix denotes a TSSOP-20 housing. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure that the operating environment remains within the specified temperature and voltage limits to maintain signal integrity and device longevity.

Latches Selection Notes

Select this component when designing systems requiring high-speed data latching at 3.3 V logic levels. The LVTH series offers improved performance over standard LVT devices. Consider the TSSOP-20 package constraints regarding PCB space and thermal dissipation requirements during layout planning.

Latches Part Context

This part belongs to the SN74LVTH573 family of octal latches. It serves as a 3.3-V ABT (Advanced BiCMOS Technology) solution. The device is designed for high-density memory and microprocessor-based systems. It replaces older generation latches with faster switching characteristics and lower power profiles.

Latches Replacement Considerations

SN74LVTH573PWR is a reel-packaged equivalent with identical electrical specifications. SN74LVTH573DBR offers the same functionality in an SSOP-20 package. Verify pin compatibility and thermal characteristics when substituting packages.
