Philips Semiconductors Product specification I2C bus extender 82B715 FUNCTIONAL DESCRIPTION APPLICATION NOTES The 82B715 bipolar integrated circuit contains two identical buffer circuits which enable I2C and similar bus systems to be extended over long distances without degradation of system performance or requiring the use of special cables.
Philips Semiconductors Product specification I2C bus extender 82B715 RATINGS Limiting values in accordance with the Absolute Maximum System (IEC 134). Voltages with respect to pin GND (DIL-8 pin 4). LIMITS SYMBOL PARAMETER MIN. MAX. UNIT VCC to GND Supply voltage range VCC –0.
Philips Semiconductors Product specification I2C bus extender 82B715 The capacitance figures for one or more individual I2C bus nodes should be multiplied by a factor of 10 times, and then added to the Buffered bus capacitance. Calculation of a new Buffered bus pull-up resistor will alllow this single pull-up resistor to act for both the included I2C bus nodes and the Buffered bus.
