Description

The P82B96TD,112 is a bipolar IC that creates a non-latching, bidirectional, logic interface between the normal I2C bus and a range of other bus configurations. It can interface I2C bus logic signals to similar buses having different voltage and current levels. For example, it can interface to the 350mA SMBus, to 3.3V logic devices, and to 15V levels and/or low impedance lines to improve noise immunity on longer bus lengths. It achieves this interface without any restrictions on the normal I2C bus protocols or clock speed. The IC adds minimal loading to the I2C bus node, and loadings of the new bus or remote I2C bus nodes are not transmitted or transformed to the local node. Restrictions on the number of I2C bus devices in a system, or the physical separation between them, are virtually eliminated
Applications:

Communications & Networking
Consumer Electronics
