TERMINOLOGY
V
DD
Most positive power supply potential.
V
SS
Most negative power supply potential in dual-supply applications.
In single-supply applications, it may be connected to GND.
V
L
Logic power supply (5 V).
GND
Ground (0 V) reference.
S
Source terminal. May be an input or an output.
D
Drain terminal. May be an input or an output.
IN
Logic control input.
R
ON
Ohmic resistance between D and S.
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 terminals D, S.
C
S
(Off)
Off switch source capacitance.
C
D
, C
S
(On)
On switch capacitance.
t
TRANSITION
Delay time between the 50% and 90% points of the digital
inputs and the switch on condition when switching from one
address state to another.
t
D
Off time or on time measured between the 90% points of both
switches when switching from one address state to the other.
V
INL
Maximum input voltage for Logic 0.
V
INH
Minimum input voltage for Logic 1.
I
INL
(I
INH
)
Input current of the digital input.
Crosstalk
A measure of unwanted signal that is coupled through from one
channel to another as a result of parasitic capacitance.
Off Isolation
A measure of unwanted signal coupling through an off channel.
I
DD
Positive supply current.
I
SS
Negative supply current.
