The PCA9518PW,118 is a BiCMOS integrated circuit from NXP Semiconductors, designed to extend I2C-bus and SMBus systems. It functions as an expandable 5-channel, bidirectional buffer, supporting active HIGH individual repeater enable inputs and open-drain inputs/outputs.
This device allows for the extension of I2C-bus by buffering both data (SDA) and clock (SCL) lines, enabling virtually unlimited buses of 400 pF. It supports lock-up-free operation, arbitration, and clock stretching across the repeater, accommodating Standard-mode and Fast-mode I2C-bus devices and multiple masters. The PCA9518PW,118 operates within a supply voltage range of 3.0 V to 3.6 V and features 5 V tolerant I2C-bus and enable pins.
Packaged in a 20-TSSOP, the PCA9518PW,118 is suitable for surface mount applications. Its I2C-bus I/O pins maintain a high-impedance state when VDD is below 2.0 V, improving partial power-down performance. Multiple PCA9518 devices can be grouped to create larger clusters using the expansion pins.
