74LVX373SJ

Latches Overview

The Fairchild Semiconductor 74LVX373SJ is an octal D-type transparent latch featuring three-state outputs, designed for low-voltage digital applications. It operates within a supply voltage range of 2.0V to 3.6V and supports data rates up to 50MHz at 3.3V. The device utilizes a 20-pin TSSOP surface-mount package with a width of 4.40mm. It includes eight latches in a single package, offering reduced power consumption compared to standard CMOS logic families while maintaining compatibility with standard I/O structures.

Latches Feature Summary

• Octal configuration providing eight independent D-type latches within a single integrated circuit package
• Three-state output capability allowing direct connection to system buses without additional buffering
• Low-voltage operation optimized for portable electronics and battery-powered devices
• Transparent latch behavior when enable signal is active, capturing data on transition

Latches Applications

• Bus-organized system applications requiring temporary data storage
• Portable consumer electronics utilizing low-voltage power supplies
• Communication equipment needing high-speed data latching capabilities
• Industrial control systems interfacing between microprocessors and peripheral devices

Latches Procurement Notes

Verify the specific suffix SJ indicates the TSSOP-20 package variant when sourcing. Confirm RoHS compliance status as manufacturing processes evolve under ON Semiconductor integration. Check for lead-free markings on physical components to ensure environmental regulation adherence. Validate pinout compatibility with existing PCB footprints before implementation.

Latches Selection Notes

Select this component when designing circuits requiring octal latching functionality at low voltages. Ensure the operating environment stays within the specified temperature range for reliable performance. Consider the propagation delay characteristics when determining suitability for high-speed synchronous designs. Verify that the three-state outputs meet the drive requirements of connected loads.

Latches Part Context

This part belongs to the 74LVX series of low-voltage CMOS logic devices manufactured by Fairchild Semiconductor. The LVX family bridges the gap between standard 5V logic and lower voltage requirements, offering improved noise immunity and power efficiency. As part of the broader 74xx logic family, it maintains pinout compatibility with other industry-standard logic functions for easy design migration.

Latches Replacement Considerations

Equivalent parts include the 74LVX373MTCX from the same manufacturer family. Cross-reference with NXP or ON Semiconductor datasheets for updated specifications following corporate acquisitions. Verify electrical parameters match exactly before substituting in existing designs.
