Overview

The primary function of the 4-bit 2-to-1 I²C multiplexer is to select either a 4-bit input ordata from a non-volatile register and drive this value onto the output pins. One additionalnon-multiplexed register output is also provided. The non-multiplexed output is latched toprevent output value changes during I²C writes to the non-volatile register. A write protectinput is provided to enable/disable the ability to write to the non-volatile register. An"override" input feature forces all outputs to logic 0.
