The PCA9641PWJ is a 2-channel I2C master demultiplexer with an integrated arbiter function, designed by NXP Semiconductors for reliable dual-master I2C-bus systems. This device ensures correct system operation even when two masters attempt to access the bus simultaneously. The arbiter intelligently selects a winning master, allowing the losing master to gain control after the winner relinquishes the bus or a reserve time expires.
Key electrical specifications include an operating voltage range of 2.3V to 3.6V, an input and output interface of 2-Wire Bus (I2C), and a capacitance of 6 pF. It operates with a supply current of 100mA and has a power dissipation of 400 mW. The device supports multiple transactions without interruption and offers a software reset function.
Packaged in a 16-TSSOP, the PCA9641PWJ is designed for surface mount applications. It operates within a temperature range of -40°C to 85°C. The demultiplexer can optionally disconnect the downstream bus after 100 ms of inactivity to prevent I2C-bus lock-ups. Interrupt outputs provide status indications for bus control and loss.
