1. General descriptionThe P82B96 is a bipolar IC that creates a non-latching, bidirectional , logic interfacebetween the normal I2C-bus and a range of other bus configurations. It can interfaceI2C-bus logic signals to similar buses having different voltage and current example, it can interface to the 350 A SMBus, to V logic devices, and to 15 Vlevels and/or low-impedance lines to improve noise immunity on longer bus achieves this interface without any restrictions on the normal I2C-bus protocols or clockspeed. The IC adds minimal loading to the I2C-bus node, and loadings of the new bus orremote I2C-bus nodes are not transmitted or transformed to the local node. Restrictionson the number of I2C-bus devices in a system, or the physical separation between them,are virtually eliminated. Transmitting SDA and SCL signals via balanced transmissionlines (twisted pairs) or with galvanic isolation (opto-coupling) is simple because separatedirectional Tx and Rx signals are provided.
