Note 2:

The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in

this data sheet.

Note 3:

Guaranteed by design.

Note 4:

∆RON = ∆RON(max) - ∆RON(min). On-resistance match between channels and flatness are guaranteed only with

specified voltages. Flatness is defined as the difference between the maximum and minimum value of on-resistance as

measured over the specified analog signal range.

Note 5:

Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at room temperature.

Note 6:

See Figure 4. Off isolation = 20log10 VCOM/VNC or VNO, VCOM = output, VNC or NO = input to off switch.

Note 7:

Between any two switches. See Figure 5.

Note 8:

Leakage testing at single supply is guaranteed by testing with dual supplies.
