SN74LVC573APWG4

Latches Overview

The SN74LVC573APWG4 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 accepts input voltages up to 5.5 V. The device features a maximum propagation delay of 6.9 ns at 3.3 V and typical output ground bounce of 2 V. It provides high drive capability for capacitive loads, supports mixed-mode signal operation, and includes Ioff circuitry for partial power-down protection.

Latches Feature Summary

• Operates across a wide voltage range from 1.65 V to 3.6 V
• Inputs accept voltages up to 5.5 V for mixed-mode compatibility
• Includes Ioff feature to prevent backflow during partial power-down
• Provides 3-state outputs designed for driving highly capacitive loads

Latches Applications

• Servers
• PC and notebook computers

Latches Procurement Notes

Verify the specific package type and temperature rating against the datasheet requirements. Confirm that the G4 suffix indicates lead-free and RoHS compliance as per manufacturer specifications. Ensure the operating environment stays within the -40°C to 125°C range for proper functionality.

Latches Selection Notes

Select this component when designing systems requiring octal latching with 3-state bus control. It is suitable for applications needing voltage translation between 5-V and 3.3-V domains. Consider its high drive current capabilities for low-impedance load driving and its fast switching speeds for high-frequency data retention tasks.

Latches Part Context

This part belongs to the SN74LVC573A family of octal transparent D-type latches. It shares functional characteristics with other variants in the series but differs in packaging and environmental ratings. The PW package denotes a Thin-Shrink Small-Outline Package (TSSOP) configuration.
