address state to another.

Off Isolation
Off isolation is a measure of unwanted signal coupling through
an off channel.
Charge Injection
Charge injection is a measure of the glitch impulse transferred
from the digital input to the analog output during switching.
Crosstalk
Crosstalk is a measure of unwanted signal that is coupled
through from one channel to another as a result of parasitic
capacitance.
Bandwidth
Bandwidth is the frequency at which the output is attenuated
by 3 dB.
On Response
On response is the frequency response of the on switch.
AC Power Supply Rejection Ratio (ACPSRR)
ACPSRR is a measure of the ability of a part to avoid coupling
noise and spurious signals that appear on the supply voltage pin
to the output of the switch. The dc voltage on the device is
modulated by a sine wave of 0.62 V p-p. The ratio of the
amplitude of the signal on the output to the amplitude of the
modulation is the ACPSRR.
