P82B715DG4

Signal Buffers, Repeaters, Splitters Overview

The P82B715DG4 is an I2C bus extender manufactured by Texas Instruments, designed to extend the range of standard I2C buses. It operates within a supply voltage range of 3 V to 12 V and supports clock frequencies up to 400 kHz. The device features a propagation delay of 250 ns and provides an output current capability of 60 mA. It is housed in an 8-SOIC surface-mount package and functions reliably across an operating temperature range from -40°C to +85°C.

Signal Buffers, Repeaters, Splitters Feature Summary

• Extends I2C bus range using emitter-follower topology to support large capacitance loads
• Provides low-impedance bus driving with increased sink capability for signal integrity
• Supports bidirectional data transfer between high-speed and low-speed I2C segments

Signal Buffers, Repeaters, Splitters Applications

• Driving twisted pair cables for very large signal distribution systems
• Extending I2C connections between microcontrollers and remote sensors over long distances
• Interfacing 3.3V logic systems with 5V I2C peripherals via cable links

Signal Buffers, Repeaters, Splitters Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices, as availability may be limited. Ensure packaging specifications match design requirements before finalizing orders.

Signal Buffers, Repeaters, Splitters Selection Notes

Select this component when extending I2C bus distance beyond standard PCB limits is required. Verify that the load capacitance and cable length fall within the device's drive capabilities. Ensure supply voltage levels align with the connected system's logic thresholds for reliable operation.

Signal Buffers, Repeaters, Splitters Part Context
