(1) Typical characteristics are at +3V supply and +25°C
(2) Flatness is defined as the difference between the maximum and minimum value of on resistance as
measured over the specified analog signal ranges.
(3) △RON= RON(MAX) - RON(MIN), between NC1 and NC2 or between NO1 and NO2.
技 indicated in the operational sections of the specifications are not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
