74LCX374MTC

Overview

The Fairchild Semiconductor 74LCX374MTC is an octal D-type flip-flop belonging to the 74LCX logic family. It features eight independent D-type inputs and a buffered clock input for synchronous data capture. The device provides three-state outputs, allowing direct connection to bus-oriented systems without external drivers. It operates within a supply voltage range of 2V to 5.5V and utilizes advanced CMOS technology for low power consumption. The component is housed in a 20-lead TSSOP surface-mount package.

Feature Summary

• Octal D-type flip-flop with separate D inputs and a common buffered clock
• Three-state outputs designed for efficient bus-oriented system interfacing
• Low power dissipation characteristics inherent to CMOS technology
• High noise immunity with TTL-compatible input thresholds

Applications

• Bus-oriented data storage applications
• Register files in digital logic circuits
• Data buffering between microprocessors and peripheral devices
• Synchronous state retention in communication interfaces

Procurement Notes

Verify that the specific part number matches the required 20-lead TSSOP package configuration. Confirm the manufacturer origin, as production may have transitioned from Fairchild Semiconductor to ON Semiconductor. Ensure the datasheet revision aligns with the intended design specifications regarding electrical characteristics and pinout compatibility.

Selection Notes

Select this component when designing systems requiring eight-bit synchronous data latching with high-speed operation. The 74LCX series is suitable for applications demanding low voltage operation down to 2V while maintaining compatibility with standard logic levels. Consider the three-state output capability if the design requires sharing a common data bus among multiple components.

Part Context

This device is part of the broader 74LCX family of low-voltage CMOS logic integrated circuits. It serves as a fundamental building block for sequential logic designs, providing reliable data storage capabilities. The MTC suffix indicates the specific thin-shrink small-outline package used for surface-mount assembly, distinguishing it from through-hole or alternative plastic package variants.

Replacement Considerations

Compatible substitutes include the MM74HC374MTC and 74ACT374MTC. These alternatives offer similar functional pinouts but differ in operating voltage ranges and propagation delay speeds. Verify that the replacement device supports the specific supply voltage requirements of the target application.
