3 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.
The PCA9515B buffers both the serial data (SDA) and serial clock (SCL) signals on the I2C bus, while retaining all the operating modes and features of the I2C system. The device allows two buses, of 400-pF bus capacitance, to be connected in an I2C application.
