74LVX374SJX

Overview

The Fairchild Semiconductor 74LVX374SJX is an octal D-type flip-flop featuring three-state outputs, designed for bus-oriented applications. It operates within a supply voltage range of 2.0V to 3.6V and supports a maximum operating frequency of 55MHz at nominal supply. The device utilizes a 20-lead TSSOP package with a width of 4.40mm. It includes buffered clock and output enable inputs common to all flip-flops, ensuring synchronized data capture on the positive edge of the clock signal.

Feature Summary

• Octal D-type flip-flop architecture with separate D-type inputs for each stage
• Three-state outputs facilitate efficient bus-oriented system designs
• Buffered clock and output enable inputs ensure signal integrity across all stages

Applications

• Bus-oriented data storage in low-voltage digital systems
• Parallel-to-serial data conversion circuits
• General-purpose memory registers in portable electronic devices

Procurement Notes

Verify that the specific suffix 'SJX' corresponds to the tape-and-reel packaging format rather than bulk or tube distribution. Confirm RoHS compliance status and moisture sensitivity level requirements for surface-mount assembly processes. Ensure the ordering part number matches the exact lead-free designation required by your manufacturing specifications.

Selection Notes

Select this component when a low-voltage (2.0V–3.6V) octal register with tri-state capability is required. It is suitable for applications demanding moderate speed performance up to 55MHz. Consider the TSSOP-20 package dimensions for PCB layout constraints. Verify input compatibility with the target logic family voltages before integration into the circuit design.

Part Context

This device belongs to the 74LVX series, representing advanced low-voltage CMOS technology from Fairchild Semiconductor. It provides a cost-effective solution for high-density digital logic applications requiring reduced power consumption. The octal configuration allows for compact implementation of multi-bit storage functions in space-constrained embedded systems.

Replacement Considerations

Equivalent parts include MC74LVX374MG from onsemi and MM74LVX374MTCX from Fairchild, provided they match the TSSOP-20 package and electrical characteristics. Cross-reference pinouts and timing parameters to ensure functional compatibility during substitution.
