7.3.1.1 Inputs with Integrated Static Pull-Down Resistors

This device has 5 MΩ typical integrated weak pull-downs for each input. This feature allows all inputs to be left floating without the concern for unstable outputs or increased current consumption. This also helps to reduce external component count for applications where not all channels are used or need to be fixed low. If an external pull-up is required, it should be no larger than 1 MΩ to avoid contention with the 5 MΩ internal pull-down.
