9.4 Detailed Design Procedure

The TMUX1204 can be operated without any external components except for the supply decoupling capacitors. If the parts desired power-up state is disabled, the enable pin should have a weak pull-down resistor and be controlled by the MCU via GPIO. All inputs being muxed to the ADC of the MCU must fall within the recommend operating conditions of the TMUX1204 including signal range and continuous current. For this design with a supply of 5 V the signal range can be 0 V to 5 V and the max continuous current can be 30 mA.
