SN74LVC573ADGVR

Latches Overview

The SN74LVC573ADGVR 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 high drive capability suitable for driving highly capacitive or low-impedance loads. It includes Ioff circuitry to prevent backflow current during partial power-down modes. The component is housed in a TVSOP-20 package and supports live insertion.

Latches Feature Summary

• Octal transparent D-type latch architecture with 3-state outputs
• Ioff feature enables partial power-down and back drive protection
• Inputs tolerate 5.5 V allowing down voltage translation
• High drive capability designed for bus drivers and registers

Latches Applications

• Servers
• PC and notebook systems
• 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 package type, lead finish, and moisture sensitivity level. Ensure the selected variant matches the required operating temperature range and RoHS compliance status for the target application environment.

Latches Selection Notes

Select this component when designing systems requiring 8-bit data latching with tri-state control. It is appropriate for applications needing 5.5 V tolerant inputs while operating at lower core voltages. Consider the TVSOP-20 package dimensions and thermal characteristics for PCB layout constraints.

Latches Part Context

This part belongs to the SNx4LVC573A family of octal transparent D-type latches. The LVC series is optimized for low-voltage CMOS operations. The 'DGV' suffix specifically denotes the TVSOP-20 package configuration used in this product code.

Latches FAQ

How does the Ioff feature function?

The Ioff circuitry disables the outputs to prevent damaging current backflow through the device when it is powered down.

What is the maximum input voltage tolerance?

The inputs accept voltages up to 5.5 V, which allows the device to support mixed-mode signal operation on all ports.
