P82B715DRG4

Signal Buffers, Repeaters, Splitters Overview

The P82B715DRG4 is a single-channel I2C bus extender manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. It operates within a supply voltage range of 3 V to 12 V and supports a maximum clock frequency of 400 kHz. The device functions as a buffer and redriver for two-wire bus interfaces, featuring an input capacitance of 3000 pF and a supply current of 22 mA. It is designed for operation across a temperature range of -40°C to +85°C. This component extends I2C bus capabilities by providing low-impedance driving to support large cable capacitances.

Signal Buffers, Repeaters, Splitters Feature Summary

• Extends I2C bus range by creating a low-impedance bus capable of supporting large capacitance loads
• Provides buffering and signal re-driving for two-wire bus interfaces
• Supports standard I2C communication speeds up to 400 kHz

Signal Buffers, Repeaters, Splitters Applications

• Driving twisted pair cables for very large signal distribution systems
• I2C bus extension in environments with high capacitive loading
• Signal buffering for I2C peripherals requiring increased sink capability

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free status as per manufacturer standards. Confirm that the 8-SOIC package dimensions match the design footprint requirements. Ensure the operating voltage range of 3 V to 12 V aligns with the target system power rails. Check for any recent Product Change Notifications (PCN) regarding assembly sites or material changes.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when existing I2C drivers cannot handle the capacitive load of long cables or multiple branches. The wide supply voltage range allows compatibility with various logic levels. Consider the 8-SOIC package size for PCB layout constraints. Verify that the 400 kHz speed meets the application's data rate requirements without excessive propagation delay.

Signal Buffers, Repeaters, Splitters Part Context

The P82B715DRG4 belongs to the P82B715 family of I2C bus extenders from Texas Instruments. It is functionally equivalent to the P82B715DR, with the 'G4' suffix denoting Green/RoHS-compliant manufacturing. Both variants share identical electrical characteristics and pinouts, differing primarily in environmental compliance documentation and packaging details.

Signal Buffers, Repeaters, Splitters Replacement Considerations

The P82B715DR is a direct functional substitute with identical specifications. Verify that the replacement part maintains the same 8-SOIC package and electrical parameters. No other cross-model substitutes are confirmed in the provided documentation.
