... NXP Semiconductors The Multiplexer function controls the six open-drain outputs, MUX_OUTx and NON_MUXED_OUT. This control is affected by the input pins MUX_SELECT (pin 19), MUX_OUT_LOW (pin 26), and/or an internal register programmed via the I Upon power-up, the multiplex function is controlled by the MUX_SELECT and MUX_OUT_LOW pins. When the MUX_SELECT signal is a logic 0, the multiplexer will select the data from the 6-bit EEPROM to drive on the MUX_OUTx and NON_MUXED_OUT pins ...
