Datasheet

On-resistance increases slightly at low supply voltages.
Maximum supply voltage (V+) must not exceed +6V.
Adding protection diode D2 causes the logic threshold
to be shifted relative to GND. Protection diodes D1 and
D2 also protect against some overvoltage situations.
With Figure 5’s circuit, if the supply voltage is below the
absolute maximum rating, and if a fault voltage up to
the absolute maximum rating is applied to an analog
signal pin, no damage results.
