DUAL BIDIRECTIONAL BUS BUFFER
SCPS144B – MAY 2006 – REVISED JULY 2007
FEATURES
• Operating Power-Supply Voltage Range
of 2 V to 15 V
• Can Interface Between I²C Buses Operating at
Different Logic Levels (2 V to 15 V)
• Supports Bidirectional Data Transfer of I²C
Bus Signals
• Allows Bus Capacitance of 400 pF on the Main
I²C Bus (Sx/Sy Side) and 4000 pF on the
Transmission Side (Tx/Ty)

DESCRIPTION/ORDERING INFORMATION
The P82B96 is a bipolar device that supports bidirectional data transfer between the normal I²C bus and a range
of other bus configurations with different voltage and current levels. It can function as the interface without any
limitations on the normal I²C operation and clock speed.
