SN74LV373ADW

Latches Overview

The SN74LV373ADW is an octal transparent D-type latch manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 5.5V and supports mixed-mode operation across all ports. The device features three-state outputs and includes Ioff support for partial power-down mode, preventing excessive current draw when VCC is de-asserted. Designed for high-speed applications, it exhibits a maximum propagation delay of 8.5ns at 5V. The component is housed in a 20-pin SOIC package and functions as a bus driver or register for data storage.

Latches Feature Summary

• Supports mixed-mode voltage operation on all ports
• Includes Ioff circuitry for partial power-down protection
• Features three-state outputs for bus-oriented designs

Latches Applications

• Printer systems
• Motor control units
• Network switches
• Server motherboards
• Wireless infrastructure equipment

Latches Procurement Notes

Verify the specific suffix 'DW' corresponds to the standard 20-pin SOIC package configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments. Ensure the ordering part number matches the required tape-and-reel or tube packaging options available for this specific variant.

Latches Selection Notes

Select this component for designs requiring octal latching with mixed-voltage port compatibility. It is suitable for applications needing partial power-down capabilities via Ioff support. Consider the 2V to 5.5V operating range and 8.5ns propagation delay for timing constraints. Verify that the SOIC-20 package fits the PCB layout requirements compared to TSSOP alternatives.

Latches Part Context

This device belongs to the SN74LV373A family of octal transparent D-type latches. It shares functional similarities with other members like the SN74LV373APWR but differs in package type. The LV series is characterized by its wide supply voltage range and mixed-mode operation capabilities, distinguishing it from standard 5V-only logic families.
