SEL1

Logic control input 1, has internal pull-down resistor. Controls channel 1 state as shown in Section

9.5.

SEL2

Logic control input 2, has internal pull-down resistor. Controls channel 2 state as shown in Section

9.5.

SEL3

Logic control input 3, has internal pull-down resistor. Controls channel 3 state as shown in Section

9.5.

SEL4

Logic control input 4, has internal pull-down resistor. Controls channel 4 state as shown in Section

9.5.

VDD

Positive power supply. This pin is the most positive power-supply potential. For reliable operation,

connect a decoupling capacitor ranging from 0.1 µF to 10 µF between VDD and GND.

VSS

Negative power supply. This pin is the most negative power-supply potential. In single-supply

applications, this pin can be connected to ground. For reliable operation, connect a decoupling

capacitor ranging from 0.1 μF to 10 μF between VSS and GND.

Thermal Pad

—

The thermal pad is not connected internally. No requirement to solder this pad, if connected it is

recommended that the pad be left floating or tied to GND

I = input, O = output, I/O = input and output, P = power.
