Most positive power supply potential.
Most negative power supply potential in dual
supplies. In single supply applications, it may be
connected to GND.
Logic power supply (+5 V).
Ground (0 V) reference.
Source terminal. May be an input or output.
Drain terminal. May be an input or output.
Logic control input.
Ohmic resistance between D and S.
On resistance match between any two channels
i.e., R

min.
Flatness is defined as the difference between the
maximum and minimum value of on-resistance as
measured over the specified analog signal range.
Source leakage current with the switch “OFF.”
Drain leakage current with the switch “OFF.”
Channel leakage current with the switch “ON.”

Delay between applying the digital control input
and the output switching on. See Test Circuit 4.
Delay between applying the digital control input
and the output switching off.
“OFF” time or “ON” time measured between
the 90% points of both switches, when switching
from one address state to another. See Test
Circuit 5.
A measure of unwanted signal coupled through
from one channel to another as a result of para-
sitic capacitance.
A measure of unwanted signal coupling through
an “OFF” switch.
A measure of the glitch impulse transferred
from the digital input to the analog output dur-
ing switching.
