SN74LVC573ADW

Latches Overview

The SN74LVC573ADW 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 supports mixed-mode signal operation, allowing 5-V I/O with a 3.3-V VCC. The SOIC-20 package provides high drive capability for driving highly capacitive or low-impedance loads.

Latches Feature Summary

• Supports mixed-mode signal operation on all ports
• Includes Ioff circuitry for partial power-down mode
• Provides buffered output-enable control

Latches Applications

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

Latches Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest Package Option Addendum to confirm the exact physical package type and carrier configuration. Ensure that the selected variant matches the required operating temperature range and lead finish specifications for the intended application environment.

Latches Selection Notes

Select this component when designing systems requiring octal data latching with high-speed performance and 3-state bus interfacing capabilities. The wide operating voltage range and 5.5-V tolerant inputs make it suitable for translating signals between different logic levels in mixed-voltage environments.

Latches Part Context

This part belongs to the SNx4LVC573A family of octal transparent D-type latches. The family includes variants designed for 2.7-V to 3.6-V operation (SN54LVC573A) and 1.65-V to 3.6-V operation (SN74LVC573A). All variants share identical functional characteristics regarding latch enable and output enable operations.
