Description : Dual bi-directional bus buffer

DESCRIPTION
The P82B96 is a bipolar IC that creates a non-latching, bi-directional, 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 350 µA SMB bus, to 3.3 V logic devices, and to 15 V levels and/or low impedance lines to improve noise immunity on longer bus lengths.

FEATURES
Bi-directional data transfer of I2C-bus signals
Isolates capacitance allowing 400 pF on Sx/Sy side and 4000 pF on Tx/Ty side
Tx/Ty outputs have 60 mA sink capability for driving low impedance or high capacitive buses
400 kHz operation over at least 20 meters of wire (see AN10148)
Supply voltage range of 2 V to 15 V with I2C logic levels on Sx/Sy side independent of supply voltage
Splits I2C signal into pairs of forward/reverse Tx/Rx, Ty/Ry signals for interface with opto-electrical isolators and similar devices that need uni-directional input and output signal paths.
Low power supply current
ESD protection exceeds 3500 V HBM per JESD22-A114, 250 V DIP package / 400 V SO package MM per JESD22-A115, and 1000 V CDM per JESD22-C101
Latch-up free (bipolar process with no latching structures)
Packages offered: DIP, SO, and TSSOP

TYPICAL APPLICATIONS
Interface between I2C buses operating at different logic levels (e.g., 5 V and 3 V or 15 V)
Interface between I2C and SMB (350 µA) bus standard.
Simple conversion of I2C SDA or SCL signals to multi-drop differential bus hardware, e.g., via compatible PCA82C250.
