TERMINOLOGY
I
Positive supply current.
V
Analog voltage on Terminal D and Terminal S.
R
Ohmic resistance between Terminal D and Terminal S.
R
Flatness is defined as the difference between the maximum and
minimum value of on resistance as measured.
∆R
On resistance match between any two channels.
I
Source leakage current with the switch off.
I
Channel leakage current with the switch on.
V
Maximum input voltage for Logic 0.
V
Minimum input voltage for Logic 1.
I
Input current of the digital input.
C
Off switch source capacitance. Measured with reference
to ground.
C
On switch capacitance. Measured with reference to ground.
C
Digital input capacitance.
t
Delay time between the 50% and the 90% points of the digital
input and switch on condition.
t
Delay time between the 50% and the 10% points of the digital
input and switch off condition.
t
On or off time measured between the 80% points of both
switches when switching from one to the other.

t
Signal propagation delay through the switch measured
between the 50% points of the input signal and its corre-
sponding output signal.
t
Difference in propagation delay between the selected inputs on
the 4:1 multiplexers or any two SPDT switches from the wide
bandwidth section.
Charge Injection
A measure of the glitch impulse transferred from the digital
input to the analog output during on-off switching.
Off Isolation
A measure of unwanted signal coupling through an off switch.
Crosstalk
A measure of unwanted signal that is coupled through from one
channel to another as a result of parasitic capacitance.
−3 dB Bandwidth
The frequency at which the output is attenuated by 3 dB.
Insertion Loss
The loss due to the on resistance of the switch.
THD + N
The ratio of the harmonic amplitudes plus signal noise to the
fundamental.
Differential Gain Error
The measure of how much color saturation shift occurs when
the luminance level changes. Both attenuation and amplification
can occur; therefore, the largest amplitude change between any
two levels is specified and expressed in percent.
Differential Phase Error
The measure of how much hue shift occurs when the luminance
level changes. It can be a negative or a positive value and is
expressed in degrees of subcarrier phase.
