SN74LVC573APWTG4

Latches Overview

The SN74LVC573APWTG4 is an octal transparent D-type latch with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage of 1.65 V to 3.6 V and features inputs that accept voltages up to 5.5 V, supporting mixed-mode signal operation. The device provides a maximum propagation delay of 6.9 ns at 3.3 V and typical output ground bounce of 2 V. It includes Ioff support for partial power-down mode and back drive protection. Latch-up performance exceeds 250 mA per JESD 17.

Latches Feature Summary

• Features 3-state outputs designed for driving highly capacitive or low-impedance loads.
• Supports mixed-mode signal operation allowing 5-V input/output voltage with 3.3-V VCC.
• Includes Ioff circuitry to prevent damaging current backflow during partial power-down.
• Provides ESD protection exceeding JESD 22 requirements across multiple test models.

Latches Applications

• Servers
• PC and notebook computers
• Network switches
• Health and fitness wearables

Latches Procurement Notes

Verify the specific package variant matches the required footprint, as the PW designation indicates a TSSOP-20 package. Confirm RoHS compliance status and lead finish details via the manufacturer's official documentation before finalizing procurement. Ensure ordering suffixes align with the desired packaging quantity and carrier type specified in the latest orderable addendum.

Latches Selection Notes

Select this component when designing systems requiring high-speed data latching with 3-state bus control capabilities. It is suitable for applications needing buffer registers, I/O ports, or bidirectional bus drivers. The wide operating voltage range and 5.5 V tolerant inputs make it ideal for interfacing between different logic voltage domains in mixed-signal environments.

Latches Part Context

This part belongs to the SNx4LVC573A family of octal transparent D-type latches. The 'SN74' prefix denotes commercial temperature range operation, while 'LVC' indicates Low-Voltage CMOS technology. The 'PW' suffix specifies the Thin Shrink Small-Outline Package (TSSOP) with 20 pins. The 'G4' suffix typically signifies Green/RoHS-compliant manufacturing.

Latches Replacement Considerations

Direct replacements within the same family include SN74LVC573ADBR, SN74LVC573ADW, and SN74LVC573ANS. Verify pin compatibility and thermal characteristics when substituting packages such as SSOP, SOIC, or SOP variants.
