PCA9600 - NXP

PCA9600 Dual Bidirectional Bus Buffer

The PCA9600 is designed to isolate I2C-bus capacitance, allowing long buses to be driven in point-to-point or multipoint applications of up to 4 000 pF. The PCA9600 is a higher-speed version of the P82B96. It creates a non-latching, bidirectional, logic interface between a normal I2C-bus and a range of other higher capacitance or different voltage bus config.

Features

• Bidirectional data transfer of I2C-bus signals
• Isolates capacitance allowing 400 pF on SX/SY side and 4 000 pF on TX/TY side
• TX/TY outputs have 60 mA sink capability for driving low-impedance or high-capacitive buses
• 1 MHz operation on up to 20 meters of wire (see AN10658)
• Supply voltage range of 2.5 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 s.
