74LVX273SJ

Overview

The Fairchild Semiconductor 74LVX273SJ is an octal D-type flip-flop featuring positive-edge triggering and true outputs. It operates within a supply voltage range of 2V to 3.6V, utilizing low-voltage CMOS technology for reduced power consumption. The device includes a common buffered clock input and an asynchronous master reset function that clears all flip-flops simultaneously. Packaged in a 16-pin SOIC (Small Outline Integrated Circuit) format, it supports surface-mount assembly with standard JEDEC MO-012 dimensions.

Feature Summary

• Octal configuration providing eight independent edge-triggered D-type flip-flops
• Common buffered clock input ensures synchronized data capture across all channels
• Asynchronous master reset functionality allows immediate clearing of stored states
• Low-voltage operation compatible with modern digital logic systems

Applications

• Data storage registers in microprocessor-based systems
• Buffering interfaces between different voltage domains
• Synchronization circuits for high-speed digital signals
• Memory address latching applications

Procurement Notes

Verify the specific suffix 'SJ' against official Fairchild or ON Semiconductor documentation to confirm package type and tape/reel specifications. Ensure compliance with RoHS directives and check moisture sensitivity levels prior to soldering. Cross-reference the manufacturer part number with current distributor catalogs to confirm availability and obsolescence status before finalizing procurement plans.

Selection Notes

Select this component when an octal latch with true outputs and low-voltage compatibility is required. Compare propagation delays and output drive capabilities against system timing requirements. Consider the 16-pin SOIC footprint for PCB layout constraints. Evaluate alternative series such as 74HC or 74HCT if higher noise immunity or different voltage thresholds are necessary for the specific application environment.

Part Context

This device belongs to the 74LVX family of low-voltage CMOS logic integrated circuits. The 74LVX series is designed for applications requiring operation at supply voltages below standard 5V logic levels. Similar parts include the 74LVX373 transparent latch and the 74LVX245 bus transceiver, offering various I/O configurations within the same low-power technology node.

Replacement Considerations

Compatible substitutes include the SN74LVX273D from Texas Instruments and the MC74LVX273DTR2G from onsemi. Verify pinout compatibility and electrical characteristics such as propagation delay and output current before implementing replacements.
