P82B715TD,118

Signal Buffers, Repeaters, Splitters Overview

The P82B715TD,118 is a bipolar I2C-bus extender manufactured by NXP Semiconductors in an 8-lead SO plastic small outline package. It provides dual bidirectional buffering for SDA and SCL lines with unity voltage gain and tenfold current amplification. The device operates within a supply voltage range of 3 V to 12 V and supports clock speeds up to 400 kHz. It increases the allowable system capacitance from 400 pF to approximately 3000 pF while maintaining logic signal levels independent of the supply voltage.

Signal Buffers, Repeaters, Splitters Feature Summary

• Dual bidirectional buffer providing tenfold current amplification without external directional control
• Compatible with I2C-bus, SMBus, PMBus, and DDC standards
• Logic signal output levels remain unchanged and independent of the supply voltage
• Provides ESD protection exceeding 2500 V HBM

Signal Buffers, Repeaters, Splitters Applications

• Extending I2C-bus communication distances using long cables or twisted-pair wiring
• Increasing total connected capacitance of an I2C-bus system to around 3000 pF
• Multi-drop distribution of I2C-bus signals in AdvancedTCA radial IPMB architectures

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required packaging format. Review the official datasheet for any recent product change notifications regarding pinout or electrical characteristics before finalizing procurement plans.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when extending bus distance via low-impedance cabling is preferred over capacitive isolation. Ensure the application does not require voltage level translation, as the device maintains input logic levels. Verify that the total system capacitance remains below 3000 pF and individual bus sections stay under 400 pF for optimal performance.

Signal Buffers, Repeaters, Splitters Part Context

This part belongs to the P82B715 family of I2C-bus extenders designed for bipolar IC applications. It retains all operating modes of the standard I2C-bus while allowing practical separation distances between components to be significantly increased. The device is intended for use in derivative bus systems requiring robust signal transmission over extended physical links.

Signal Buffers, Repeaters, Splitters Replacement Considerations

Direct substitutes include the P82B715DR and P82B715P from Texas Instruments. Alternative options are the P82B96DGKR and P82B96P, though these utilize different isolation mechanisms.
