Note:

(1). Typical characteristics are at 25°C

(2). Guaranteed by design. Resistance measurement do not include test circuit or package resistance

(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). △RON= RON(MAX) - RON(MIN) between channels
