PCA8550 4-bit multiplexed/1-bit latched 5-bit I2C EEPROM

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 ch.
