PCA9515A - Texas Instruments

PCA9515A Dual Bidirectional I2C Bus and SMBus Repeater

This dual bidirectional I2C buffer is operational at 2.3V to 3.6-V VCC. The PCA9515A is a BiCMOS integrated circuit intended for I2C bus and SMBus systems applications. The device contains two identical bidirectional open-drain buffer circuits that enable I2C and similar bus systems to be extended without degradation of system performance. The PCA9515A buffe.
