Features and Applications

The P82B715PN,112 is a part of P82B series I2C Bus. It has an operating temperature ranging from -40 °C to +85 °C and comes in SOIC-8 package.

The P82B715 is a bipolar IC intended for application in IC-bus and derivative bus systems. While retaining all the operating modes and features of the IC-bus it permits extension of the practical separation distance between components on the I2C-bus by buffering both the data (SDA) and the clock (SCL) lines.


  • Dual, bidirectional, unity voltage gain buffer with no external directional control required
  • Compatible with I2C-bus and its derivatives SMBus, PMBus, DDC, etc.
  • Logic signal levels may include (but not exceed) both supply and ground
  • Logic signal input voltage levels are output without change and are independent of VCC
  • x10 impedance transformation, but does not change logic voltage levels
  • Supply voltage range 3 V to 12 V
  • Clock speeds to at least 100 kHz and 400 kHz when other system delays permit
  • ESD protection exceeds 2500 V HBM per Mil. Std 883C-3015.7 and 400 V MM per JESD22-A115 (I/Os have diodes to VCC and GND)
  • Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA


  • Increase the total connected capacitance of an I2C-bus system to around 3000 pF
  • Drive IC-bus signals over long cables to approximately 50 meters or 3000 pF
  • Drives x10 lower impedance bus wiring for improved noise immunity
  • Multi-drop distribution of IC-bus signals using low cost twisted-pair cables
  • AdvancedTCA radial IPMB architecture
  • Driving 30 mA Fm+ devices from standard 3 mA parts
