• Designed specifically for bus-oriented applications
• Operates on low voltage supply ranging from 2V to 3.6V

Applications

• Bus-oriented data transmission systems
• Low voltage digital circuit interfaces
• Octal bidirectional buffer implementations

Procurement Notes

Verify the specific manufacturer designation, as ON Semiconductor has acquired Fairchild's semiconductor business. Confirm the package type is 20-SOP and check the lifecycle status, as some sources indicate this component may be obsolete or discontinued by the original manufacturer. Ensure compatibility with your required voltage and temperature specifications before procurement.

Selection Notes

Select this component when an octal bidirectional transceiver is required for bus applications. It is suitable for systems operating between 2V and 3.6V. Consider the 20-SOP surface mount package for PCB layout constraints. Verify if the 3-state output functionality meets the system's isolation requirements during inactive periods.

Part Context

This part belongs to the LVQ series of low voltage logic devices. It functions as an octal bus transceiver, allowing data flow control via direction and enable inputs. The device is fabricated using CMOS technology to ensure low power dissipation while maintaining high-speed operation suitable for modern digital systems.

Replacement Considerations

Check for equivalents such as the 74LVQ245SJX variant. Other manufacturers may offer compatible octal transceivers, but verify pinout and electrical characteristics match exactly.
