8.3.5 Integrated Pull-Down Resistor on Logic Pins

The TMUX9612 has internal weak Pull-Down resistors to GND to ensure the logic pins are not left floating. The value of this Pull-Down resistor is approximately 4MΩ, but is clamped to 1µA at higher voltages. This feature integrates up to four external components and reduces system size and cost.
