Overview
The PCA9617ATPZ, manufactured by NXP USA Inc., is a CMOS integrated circuit designed as a level translating Fm+ I2C-bus repeater. This device is engineered to extend the reach of the I2C bus by providing bidirectional buffering for both the data (SDA) and the clock (SCL) lines. It supports voltage level translation between low voltage (0.8 V to 5.5 V) and higher voltage (2.2 V to 5.5 V) systems, making it versatile for various applications where different voltage levels are required.
