General Description

The PCA9515B is a BiCMOS dual bidirectional buffer integrated circuit intended for I2C bus and SMBus applications.

The device contains two identical bidirectional open-drain buffer circuits that enables I2C and similar bus systems to be extended (or add slaves) without degrading system performance.

The dual bidirectional I2C buffer is operational at 2.3 V to 3.6 V VCC.
