PCA9600

Dual bidirectional bus buffer

Rev. 5 — 5 May 2011

Product data sheet

1. General description

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 4000 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 configurations. It can operate at speeds up to at least 1 MHz, and the high drive side

is compatible with the Fast-mode Plus (Fm+) specifications.

The PCA9600 features temperature-stabilized logic voltage levels at its SX/SY interface

making it suitable for interfacing with buses that have non I²C-bus-compliant logic levels

such as SMBus, PMBus, or with microprocessors that use those same TTL logic levels.

The separation of the bidirectional I²C-bus signals into unidirectional TX and RX signals

enables the SDA and SCL signals to be transmitted via balanced transmission lines

(twisted pairs), or with galvanic isolation using opto or magnetic coupling. The TX and RX

signals may be connected together to provide a normal bidirectional signal.

2. Features and benefits

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

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 supply current

ESD protection exceeds 4500 V HBM per JESD22-A114 and 1400 V CDM per

JESD22-C101

Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA

Packages offered: SO8 and TSSOP8 (MSOP8)
