FUNCTION DESCRIPTION

I

The S524AB0X91/B0XB1 supports the I

consists of a serial data line (SDA) and a serial clock line (SCL). The SDA and the SCL lines must be connected

to V

Any device that puts data onto the bus is defined as a “transmitter” and any device that gets data from the bus is

a “receiver.” The bus is controlled by a master device whic h generates the serial clock and start/stop conditions,

controlling bus access. Using the A0, A1, and A2 input pins, up to eight S524AB0X91/B0XB1 devices can be

connected to the same I

transmitter or a receiver, but the master device determines which bus operating mode would be active.
