Product Summary

The P82B96TD 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. The P82B96TD can interface I2C-bus logic signals to similar buses having different voltage and current levels. The applications of the P82B96TD include Interface between I2C buses operating at different logic levels, Interface between I2C and SMB bus standard, Simple conversion of I2C SDA or SCL signals to multi-drop differential bus hardware, e.g., via compatible PCA82C250 and Interfaces with Opto-couplers to provide Opto isolation between I2C-bus nodes up to 400 kHz.

Parametrics

P82B96TD absolute maximum ratings: (1)VCC to GND, Supply voltage range VCC: –0.3 to +18 V; (2)Vbus, Voltage range on I2C Bus, SDA or SCL: –0.3 to +18 V; (3)VTx, Voltage range on buffered output: –0.3 to +18 V; (4)VRx, Voltage range on receive input: –0.3 to +18 V; (5)I, DC current (any pin): 250 mA; (6)Rtot, Power dissipation: 300 mW; (7)Tstg, Storage temperature range: –55 to +125℃; (8)Tamb, Operating ambient temperature range: –40 to +85℃.

Features

P82B96TD features: (1)Bi-directional data transfer of I2C-bus signals; (2)Isolates capacitance allowing 400 pF on Sx/Sy side and 4000 pF on Tx/Ty side; (3)Tx/Ty outputs have 60 mA sink capability for driving low impedance or high capacitive buses; (4)400 kHz operation over at least 20 meters of wire; (5)Supply voltage range of 2 V to 15 V with I2C logic levels on Sx/Sy side independent of supply voltage; (6)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; (7)Low power supply current; (8)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; (9)Latch-up free (bipolar process with no latching structures); (10)Packages offered: DIP, SO, and TSSOP.
