The switch output control
All switch inputs (SWx) are pulled down by a 300 kΩ. If the generic SWx pin is left floating or connected to GND
or polarized at low logic level, the corresponding outputs will be in OFF condition. If SWx pin is connected to VDD
or polarized at high logic level, the corresponding outputs will be in ON condition. See below the complete truth
table:
