Dual Bidirectional Bus Buffer

PCA9600 Active

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.

Features

Key Features

  • idirectional 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 3500 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

This bus is called the Inter-IC or I2C-bus. Only two bus lines are required: a serial data line (SDA) and a serial clock line (SCL). Serial, 8-bit oriented, bidirectional data transfers can be made at up to 100 kbit/s in the Standard-mode, up to 400 kbit/s in the Fast-mode, up to 1 Mbit/s in the Fast-mode Plus (Fm+), or up to 3.4 Mbit/s in the High-speed mode.
