Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix 'ISC6' against official Analog Devices documentation to confirm the industrial temperature grade and SC-70-6 package variant. Ensure the order includes the '#TRMPBF' designation if tape and reel packaging is required. Confirm RoHS compliance status directly with the manufacturer's latest datasheet before procurement.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when automotive-grade reliability is required for I2C interfaces. Verify that the operating voltage matches the system's 1.6V to 5.5V range. Consider the 6-pin SC-70-6 package constraints for PCB layout. Ensure the 400 kHz speed requirement aligns with the application's data rate needs.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the LTC4311 family of I2C logic buffers. It shares functional similarities with other members like the LTC4311IDC but differs in package type and temperature rating. The ISC6 suffix denotes the industrial temperature range and specific physical package configuration compared to commercial variants.

Signal Buffers, Repeaters, Splitters Replacement Considerations

Direct substitutes include other parts within the LTC4311 family such as the LTC4311IDC#TRMPBF, provided the package and temperature requirements are compatible. Verify pinout compatibility and electrical specifications before substitution.
