MM74HC373SJ

Latches Overview

The MM74HC373SJ is an octal transparent latch manufactured by Fairchild Semiconductor, belonging to the 74HC series of high-speed CMOS logic devices. It features three-state outputs designed for bus-oriented systems, allowing multiple latches to be connected directly to a microprocessor bus. The device operates with a supply voltage range of 2.0V to 6.0V and includes separate clock and output enable inputs to control data transparency and output states independently.

Latches Feature Summary

• Octal configuration providing eight independent D-type latches within a single package
• Three-state outputs compatible with system bus architectures for efficient data transfer
• High noise immunity characteristics inherent to CMOS technology operation

Latches Applications

• Parallel data storage in digital communication interfaces
• Buffering and registration of address/data buses in microprocessor systems
• Portable battery-powered equipment requiring low power consumption

Latches Procurement Notes

Verify the specific suffix 'SJ' against manufacturer documentation to confirm package type and tape/reel specifications. Ensure compatibility with operating temperature ranges required for the target application. Cross-reference pinouts with current datasheets to account for potential revisions in manufacturing standards or lead configurations.

Latches Selection Notes

Select this component when an octal latch with three-state outputs is required for bus isolation. Consider the 74HC series performance metrics regarding speed and power dissipation relative to alternative logic families. Evaluate supply voltage constraints to ensure operation within the specified 2.0V to 6.0V range for optimal functionality.

Latches Part Context

This part belongs to the Fairchild 74HC family of high-speed CMOS logic, which offers performance comparable to TTL while maintaining low power consumption.
