UNITS
Note 2:
Typical values are for
design aid only,
are not guaranteed and are not subject to production testing. 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:
On-resistance match between channels and flatness are guaranteed only with bipolar-supply operation. Flatness is defined
as the difference between the maximum and the minimum value of on-resistance as measured at the extremes of the speci-
fied analog signal range.
Note 5:
Leakage parameters I
S(OFF)
, I
D(OFF)
, I
D(ON)
, and IS
(ON)
, are100% tested at the maximum rated hot temperature and guaranteed at +25°C.
Note 6:
Off-Isolation Rejection Ratio = 20log (V
D
/V
S
), V
D
= output, V
S
= input to off switch.
Note 7:
Between any two switches.
