Description
The IML3112 is a 1:2 Bus Expander with integrated temperature sensor for I3C/I²C bus. The input HSDA/HSCL pair can fan out to two output pairs (or channels), either individual output channel can be selected. Applications with slave devices that share the same address can use this multiplexer to prevent slave address conflicts. By selecting the proper output channel, the I3C/I²C master can access a large number of devices across both ports.
