NXP Semiconductors P82B96
The P82B96 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 I2Cbus logic signals to similar buses having different voltage and current levels. For example, it can interface to the 350 μA SMBus, to 3.3 V logic devices, and to 15 V levels and/or low-impedance lines to improve noise immunity on longer bus lengths.| Part No. | P82B96 |

FEATURES
● Bidirectional 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-bus logic levels on Sx/Sy side independent of supply voltage
● Splits I2C-bus signal into pairs of forward/reverse Tx/Rx, Ty/Ry signals for interface with opto-electrical isolators and similar devices that need unidirectional input and output signal paths.
● Low power supply current
● ESD protection exceeds 3500 V HBM per JESD22-A114 and 1000 V CDM per JESD22-C101
● Latch-up free (bipolar process with no latching structures)
● Packages offered: SO8 and TSSOP8 3
APPLICATIONS
● Interface between I2C-buses operating at different logic levels (for example, 5 V and 3 V or 15 V)● Interface between I2C-bus and SMBus (350 µA) standard NXP Semiconductors P...
