74LCX373MSAX

Latches Overview

The Fairchild Semiconductor 74LCX373MSAX is an octal transparent D-type latch featuring three-state outputs, designed for low-voltage applications. It operates within a supply voltage range of 2.0 V to 3.6 V and utilizes advanced CMOS technology to achieve high-speed performance with minimal power dissipation. The device incorporates Schmitt-trigger inputs on all channels to ensure noise immunity and stable switching characteristics. Packaged in a 20-lead SSOP format, it supports surface-mount installation and functions reliably across an industrial temperature range from -40°C to +85°C.

Latches Feature Summary

• Octal configuration providing eight independent transparent D-type latches with shared control signals
• Three-state output architecture enabling direct bus interfacing and system-level isolation
• Schmitt-trigger input design enhancing signal integrity by filtering electrical noise

Latches Applications

• Bus-oriented memory systems requiring data storage and retrieval
• Clock buffering and timing synchronization circuits
• Mobile and portable equipment utilizing low-voltage logic families

Latches Procurement Notes

Verify the specific manufacturer origin as this component was originally produced by Fairchild Semiconductor, which has undergone corporate restructuring. Confirm RoHS compliance status and check for obsolescence notices or lifecycle changes associated with current inventory sources. Ensure the package marking aligns with the original Fairchild specifications rather than subsequent licensee markings.

Latches Selection Notes

Select this component when designing systems that require high-density data latching at low operating voltages. The inclusion of Schmitt triggers makes it suitable for environments with noisy signal lines. Compare propagation delay specifications against system clock requirements to ensure timing margins are met. Verify that the 20-SSOP footprint matches the target PCB layout constraints.

Latches Part Context

This part belongs to the 74LCX series, representing low-voltage CMOS logic optimized for 3.3 V systems while maintaining compatibility with legacy interfaces. The 74LCX373 variant specifically provides octal latching capabilities, distinguishing it from simpler buffer or gate configurations within the same family. It serves as a foundational building block for digital data path management in modern electronic architectures.

Latches Replacement Considerations

Direct replacements include the ON Semiconductor version designated as 74LCX373MSAX, which shares identical pinouts and functional specifications. Other compatible alternatives may exist under different manufacturer prefixes but must be validated for electrical parameter equivalence.
