P82B96TD,118

Product Summary

The P82B96TD,118 is a bipolar IC that creates a non-latching, bidirectional, logic interface between the normal I2C-bus and a range of other bus configurations. The P82B96TD,118 can interface I2C-bus logic signals to similar buses having different voltage and current levels. For example, it can interface to the 350 μA SMBus, to 3.3 V logic devices, and to 15 V levels and/or low-impedance lines to improve noise immunity on longer bus lengths. The P82B96TD,118 achieves this interface without any restrictions on the normal I2C-bus protocols or clock speed. The applications of the P82B96TD,118 are Interface between I2C-buses operating at different logic levels, Interface between I2C-bus and SMBus standard, Simple conversion of I2C-bus SDA or SCL signals to multi-drop differential bus hardware,Interfaces with opto-couplers to provide opto-isolation between I2C-bus nodes up to 400 kHz.
