The P82B96TD/S900,118 is a dual bi-directional Bus Buffer creates a non-latching, bi-directional, 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. It achieves this interface without any restrictions on the normal IC-bus protocols or clock speed. The IC adds minimal loading to the IC-bus node and loadings of the new bus or remote IC-bus nodes are not transmitted or transformed to the local node. Restrictions on the number of IC-bus devices in a system or the physical separation between them is virtually eliminated. Transmitting SDA and SCL signals via balanced transmission lines (twisted pairs) or with galvanic isolation is simple because separate directional Tx and Rx signals are provided. The Tx and Rx signals may be directly connected without causing latching, to provide an alternative bi-directional signal line with IC-bus properties.
Bidirectional data transfer of I2C-bus signals
Isolates capacitance allowing 400pF on Sx/Sy side and 4000 pF on Tx/Ty side
Tx/Ty outputs have 60mA sink capability for driving low-impedance or high capacitive buses
