PCA9600DP,118

The NXP Semiconductors PCA9600DP,118 is a dual bidirectional bus buffer designed to isolate I2C-bus capacitance, enabling longer buses in point-to-point or multipoint applications. It operates at speeds up to 1 MHz and is compatible with Fast-mode Plus (Fm+) specifications.

This device features temperature-stabilized logic voltage levels, making it suitable for interfacing with buses that have non-I2C-bus-compliant logic levels such as SMBus or PMBus. The PCA9600 separates bidirectional I2C signals into unidirectional TX and RX signals, allowing transmission via balanced lines or galvanic isolation. It supports a supply voltage range of 2.5 V to 15 V, with I2C-bus logic levels on the SX/SY interface being independent of the supply voltage.

The PCA9600DP,118 is available in an 8-TSSOP package and is designed for surface mount applications. Its features include a 60 mA sink capability on TX/TY outputs for driving high-capacitive buses and ESD protection exceeding 3500 V HBM.

Key applications include interfacing between I2C-buses operating at different logic levels, interfacing with SMBus or Fm+ standards, and enabling long-distance point-to-point or multipoint architectures.
