)
A measure of unwanted signal which is coupled
from the digital input to the analog output
Most positive power supply potential.
Most negative power supply potential in dual
supplies. In single supply applications, it may
be connected to ground.
Ground (0 V) reference.
Ohmic resistance between D and S.
Difference between the R
channels.
Source leakage current when the switch is off.
Drain leakage current when the switch is off.
Channel leakage current when the switch is on.
Analog voltage on terminals D, S.
Channel input capacitance for “OFF”
condition.
Channel output capacitance for “OFF”
condition.
Digital input capacitance.
Delay time between the 50% and 90% points of
the digital input and switch “ON” condition.
Delay time between the 50% and 90% points of
the digital input and switch “OFF” condition.
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.
“OFF” time measured between the 80% point
of both switches when switching from one
address state to another.
Maximum input voltage for Logic “0.”
Minimum input voltage for Logic “1.”
Input current of the digital input.
through from one channel to another as a result
of parasitic capacitance.
A measure of unwanted signal coupling through
an “OFF” channel.
A measure of the glitch impulse transferred
during switching.
Positive supply current.
Negative supply current.
