1. ∆RON = RON(MAX) - RON(MIN).

2. Flatness is defined as the difference between the maximum and the minimum value of ON-resistance as measured

over the specified analog signal ranges.

3. Guaranteed by design.

4. Off-Isolation = 20log10(VCOMx/VNOx), VCOMx = output, VNOx = input to off switch.

5. Between two switches.
