V
IH
Minimum input voltage for logic HIGH.
V
IL
Minimum input voltage for logic LOW.
I
IH
(I
IL
) Input current of the digital input.
I
OS
Minimum short circuit current for S1, S2 and D.
t
ON
Propagation delay measured between 50% of the digital input to 90% of the analog output when switch is
turned ON. The peak analog voltage is 0.714V.
t
OFF
Propagation delay measured between 50% of the digital input to 90% of the analog output when switch is
turned OFF. The peak analog voltage is 0.714V.
B
W
Frequency response of the switch in the ON state measured at 3dB down.
X
TALK
Is an unwanted signal coupled from channel to channel. Measured in –dB. X
TALK
= 20 LOG V

IN
.
This is non-adjacent crosstalk.
D
G
Differential gain is the difference measurement between two bias levels, for instance analog input signals of
0V to 0.714V.
D
P
Differential phase is the difference measurement between two bias levels, for instance analog input signals
of 0V to 0.714V.
O
IRR
Off isolation is the resistance (measured in –dB) between the input and output with the switch off (NO).
