DESCRIPTION

· The PCA9515B is a BiCMOS dual bidirectional buffer IC for I2C bus and SMBus applications.
· It contains two identical bidirectional open-drain buffer circuits for extending I2C systems.
· Operational at 2.3V to 3.6V VCC, it buffers SDA and SCL signals while retaining I2C system features.
· Allows connection of two buses with 400-pF bus capacitance in I2C applications.
