TRANSITION
Delay time measured between the 50% and
90% points of the digital inputs and the switch
“ON” condition when switching from one
address state to another

of the EN digital input and the Switch “ON”
condition
t
OFF
(EN) Delay time between the 50% and 90% points

condition
t
OPEN
“OFF” Time measured between the 80% points
of both switches when switching from one
address state to another
Charge Measure of the glitch impulse transferred from
Injection the digital input to the analog output during
switching
OFF Isolation Measure of unwanted signal coupling through
an “OFF” switch
Crosstalk Measure of unwanted signal that is coupled
through from one channel to another as a result
of parasitic capacitance
Bandwidth Frequency at which the output is attenuated
by 3 dB
ON Response Frequency response of the “ON” Switch
Insertion Loss due to the ON Resistance of
Loss the switch
