TERMINOLOGY
R
ON
Ohmic resistance between D and S.
ΔR
ON
On resistance match between any two channels, that is, R
ON
maximum minus R
ON
minimum.
R
FLAT(ON)
Flatness is defined as the difference between the maximum and
minimum value of on resistance, as measured over the specified
analog signal range.
I
S
(OFF)
Source leakage current with the switch off.
I
D
(OFF)
Drain leakage current with the switch off.
I
D
, I
S
(ON)
Channel leakage current with the switch on.
V
D
(V
S
)
Analog voltage on Terminal D and Terminal S.
C
S
(OFF)
Off switch source capacitance.
C
D
(OFF)
Off switch drain capacitance.
C

(ON), C
S
(ON)
On switch capacitance.
t
ON
Delay between applying the digital control input and the output
switching on. See
Figure 19.
t
OFF
Delay between applying the digital control input and the output
switching off.
t
D
Off time or on time measured between the 90% points of both
switches, when switching from one address state to another. See
Figure 20.
Crosstalk
A measure of unwanted signal coupled through from one
channel to another as a result of parasitic capacitance.
Off Isolation
A measure of unwanted signal coupling through an off switch.
Charge Injection
A measure of the glitch impulse transferred from the digital
input to the analog output during switching.
