OPERATING RATINGS

Nominal Supply Voltage

1.8V to 5.5V

IN Voltage (regardless of supply)

−0.3V to 5.5V

Temperature Range

−40°C to 85°C

(1)

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is intended to be functional, but specific performance is not guaranteed.

(2)

All voltages are with respect to GND, unless otherwise specified.

ΔRON is equal to the difference between NC1/NC2 RON or NO1/NO2 RON at a specified voltage.

(3)

Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the specified analog

signal ranges.

(4)

Off-isolation = 20 log10(VCOM/ VNO), where VCOM = output, VNO = input switch off.
