There is no connection between the analog signal
paths and GND. V+ and GND power the internal logic
and logic-level translators, and set both the input and
output logic limits. The logic-level translators convert
the logic levels into switched V+ and GND signals to
drive the gates of the analog signals. This drive signal
is the only connection between the logic supplies (and
signals) and the analog supplies. V+ has an ESD-pro-
tection diode to GND.
These devices operate from a single supply between
+2V and +12V. At room temperature, they actually
“work” with a single supply at near or below +1.7V,
although as supply voltage decreases, switch on-resis-
tance and switching times become very high.

In 50
to 50MHz (see Typical Operating Characteristics).
Above 20MHz, the on-response has several minor
peaks, which are highly layout dependent. The problem
is not turning the switch on, but turning it off. The off-
state switch acts like a capacitor, and passes higher
frequencies with less attenuation. At 10MHz, off-isola-
tion is about -50dB in 50
(approximately 20dB per decade) as frequency
increases. Higher circuit impedances also degrade off-
isolation. Adjacent channel attenuation is about 3dB
above that of a bare IC socket, and is entirely due to
capacitive coupling.
