PCA9517D TI I2C Buffer | 8-SOIC | 2.3V-5.5V, 400kHz

Product Overview

The PCA9517D from Texas Instruments is a CMOS integrated circuit designed for I2C bus buffering and level shifting. It provides bidirectional voltage translation between two I2C buses operating at different voltage levels, supporting a wide supply range from 2.3V to 5.5V. The device is housed in an 8-pin SOIC package and is capable of operating at up to 400 kHz bus frequency. It features a built-in rise time accelerator and is compatible with standard I2C and SMBus protocols.
