NXP P82B96DPZ

P82B96DPZ is a dual bidirectional bus buffer. It 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. 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. Application includes interface between I²C-buses operating at different logic levels, interface between I²C-bus and SMBus (350µA) 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 400KHz.
