Features & Applications

The P82B96TD,118 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 P82B96 is a bipolar IC that creates a non-latching, bidirectional, logic interface between the normal IC-bus and a range of other bus configurations. It can interface IC-bus logic signals to similar buses having different voltage and current levels.


  • Bidirectional data transfer of IC-bus signals
  • Isolates capacitance allowing 400 pF on Sx/Sy side and 4000 pF on Tx/Ty side
  • Tx/Ty outputs have 60 mA sink capability for driving low-impedance or high capacitive buses
  • 400 kHz operation over at least 20 meters of wire
  • Supply voltage range of 2 V to 15 V with IC-bus logic levels on Sx/Sy side independent of supply voltage
  • Splits IC-bus signal into pairs of forward/reverse Tx/Rx, Ty/Ry signals for interface with opto-electrical isolators and similar devices that need unidirectional input and output signal paths
  • Low power supply current
  • ESD protection exceeds 3500 V HBM per JESD22-A114, 250 V DIP package, 400 V SO package MM per JESD22-A115, and 1000 V CDM per JESD22-C101
  • Latch-up free (bipolar process with no latching structures)
  • Packages offered: DIP8, SO8 and TSSOP8


  • Interface between I²C-buses operating at different logic levels
  • Interface between I²C-bus and SMBus (350 µA) standard
  • Simple conversion of I²C-bus SDA or SCL signals to multi-drop differential bus hardware, for example, via compatible PCA82C250
  • Interfaces with opto-couplers to provide opto-isolation between I²C-bus nodes up to 400 kHz
