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