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

On switch capacitance.
t
Delay between applying the digital control input and the output
switching on. See Figure 19.
t
Delay between applying the digital control input and the output
switching off.
t
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.
