Negative supply current.
GND
Ground (0 V) reference.
Sx
Source terminal. May be an input or an output.
Dx
Drain terminal. May be an input or an output.
R
ON
Ohmic resistance between Dx and Sx.
ΔR
ON
On resistance match between any two channels, for example,
R
ON
max − R
ON
min.
R
FLAT(ON)
Flatness is defined as the difference between the maximum and
minimum values of on resistance as measured over the specified
analog signal range.
I

is measured with reference
to ground.
C
IN
Digital input capacitance.
t
ON
Delay time between loading new data to the shift register and
selected switches switching on.
t
OFF
Delay time between loading new data to the shift register and
selected switches switching off.
Off Isolation
A measure of unwanted signal coupling through an off switch.
Crosstalk
A measure of unwanted signal that is coupled through from one
channel to another because of parasitic capacitance.
Charge Injection
A measure of the glitch impulse transferred from the digital
input to the analog output during switching.
Bandwidth
The frequency at which the output is attenuated by −3 dB.
On Response
The frequency response of the on switch.
Insertion Loss
The loss due to the on resistance of the switch. Insertion loss =
20 log
