74LCX374SJ

Overview

The Fairchild Semiconductor 74LCX374SJ is an octal D-type flip-flop featuring 3-STATE outputs, designed for bus-oriented applications. It operates within a supply voltage range of 2V to 3.6V and utilizes a 14-pin Small Outline Package (SOP). The device integrates buffered positive edge-triggered clock inputs and common output enable controls for all eight flip-flops. It provides TTL-compatible inputs and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Octal D-type flip-flop architecture with separate data inputs for each stage
• Three-state outputs enabling efficient bus-oriented system designs
• Buffered clock input and common output enable control for synchronized operation

Applications

• Bus-oriented data storage systems
• Parallel-to-serial data conversion interfaces
• General-purpose register applications in low-voltage logic circuits

Procurement Notes

Verify the specific suffix 'SJ' against official Fairchild or onsemi documentation to confirm package dimensions and tape/reel specifications. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing standards. Cross-reference the manufacturer part number with current distributor catalogs to confirm availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring octal storage with tri-state bus capabilities at low voltages between 2V and 3.6V. It serves as a suitable alternative to higher voltage counterparts like the 74HC374 when power consumption and voltage levels are critical constraints. Consider the SOP-14 package size for space-constrained surface-mount layouts.

Part Context

This device belongs to the 74LCX series of advanced low-voltage CMOS logic components. It shares functional similarities with other octal flip-flops such as the 74AC374 and 74VHC374 but is optimized for lower operating voltages. The series is characterized by high noise immunity and compatibility with standard logic families while maintaining low power dissipation.

Replacement Considerations

Compatible substitutes include the 74LCX374MTCX and 74LCX374SCX. Verify pinout compatibility and electrical characteristics before substitution.
