NXP PCA9517ADP118 I2C Level Repeater

The PCA9517A is a level translating I2C-bus repeater supporting voltage level shifting from as low as 0.9 V to 5.5 V, allowing reliable communication between low-voltage and high-voltage I2C or SMBus systems. It provides bidirectional buffering on both data (SDA) and clock (SCL) lines, supports multiple bus configurations including star and series topologies, and features overvoltage tolerance, open-drain outputs, and lock-up free operation. Suitable for 400 kHz systems, it ensures system integrity with robust ESD protection exceeding 5500 V HBM, and is available in various small-outline packages including SO8, TSSOP8, and HWSON8.
