PCA9515AD TI I2C Buffer | 8-SOIC | 2.3V-3.6V, 400kHz

Product Overview

The PCA9515AD from Texas Instruments is a CMOS integrated circuit designed for I2C bus and SMBus applications. It provides bidirectional voltage-level translation (up to 3.6V) and bus buffering, enabling connection of multiple devices with different voltage levels while maintaining signal integrity. Housed in an 8-pin SOIC package, it operates over a wide temperature range and supports standard and fast-mode I2C up to 400kHz.
