NOTES:
9. VLOGIC = Input voltage to perform proper function.
10. The algebraic convention, whereby the most negative value is a minimum and the most positive a maximum, is used in this
data sheet.
11. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established
by characterization and are not production tested.
12. Flatness is defined as the difference between maximum and minimum value of ON-resistance over the specified analog signal
range.
13. rON matching between channels is calculated by subtracting the channel with the highest max rON value from the channel
with lowest max rvalue.
14. Limits established by characterization and are not production tested.
Test Circuits and Waveforms
Logic input waveform is inverted for switches that have the
opposite logic sense.

Repeat test for all switches. CL includes fixture and stray
capacitance.
