PARAMETER DEFINITIONS
PARAMETER DESCRIPTION
R
ON
Resistance between the D and S ports, with the switch in the ON state
I
OZ
Output leakage current measured at the D and S ports, with the switch in the OFF state
I
OS
Short-circuit current measured at the I/O pins
V
IN
Voltage at IN
V
EN
Voltage at EN
C
IN
Capacitance at the control (EN, IN) inputs
C
OFF
Capacitance at the analog I/O port when the switch is OFF
C
ON
Capacitance at the analog I/O port when the switch is ON
V
IH
Minimum input voltage for logic high for the control (EN, IN) inputs
V
IL
Maximum input voltage for logic low for the control (EN, IN) inputs
V
IK
I/O and control (EN, IN) inputs diode clamp voltage
V
I
Voltage applied to the D or S pins when D or S is the switch input
V
O
Voltage applied to the D or S pins when D or S is the switch output
I
IH
Input high leakage current of the control (EN, IN) inputs
I
IL
Input low leakage current of the control (EN, IN) inputs
I
I
Current into the D or S pins when D or S is the switch input
I
O
Current into the D or S pins when D or S is the switch output
I
off
Output leakage current measured at the D or S ports, with V
CC
= 0
t
pds
Propagation delay measured between S1
x
and S2
x
under the specified conditions, measured from 50% of the digital
input to 90% of the analog output
B
W
Frequency response of the switch in the ON state, measured at −3 dB
X
TALK
Unwanted signal coupled from channel to channel. Measured in −dB. X
TALK
= 20 log V
O
/V
I
. This is a nonadjacent
crosstalk.
O
IRR
OFF isolation is the resistance (measured in −dB) between the input and output with the switch OFF.
D

Magnitude variation between analog input and output pins when the switch is ON and the DC offset of composite video
signal varies at the analog input pin. In NTSC standard, the frequency of the video signal is 3.58 MHz, and DC offset is
from 0 to 0.714 V.
D
P
Phase variation between analog input and output pins when the switch is ON and the DC offset of composite video
signal varies at the analog input pin. In NTSC standard, the frequency of the video signal is 3.58 MHz, and DC offset is
from 0 to 0.714 V.
I
CC
Static power-supply current
I
CCD
Variation of I
CC
for a change in frequency in the control (EN, IN) inputs
∆I
CC
Increase in supply current for each control input that is at the specified voltage level, rather than V
CC
or GND
