CMCPCI102B
Performance Information
Resistance Variation with Input Voltage
The series resistance R
S
varies with input voltage and
supply voltage, as shown in
Figure 1
.
Figure 1. Resistance Variation vs. Input Voltage
Resistance Variation with Temperature
The series resistance R
S
also varies with temperature,
as shown in
Figure 2
.
Figure 2. Resistance Variation vs. Temperature
CAP Pin Capacitance
Some external capacitance is necessary to prevent the
voltage on the CAP pin from falling during sustained
data transfers through the device. This ensures that the
logic 1 level does not degrade.
The time required to open and close the series switch,
SWs, varies according to how much capacitance is
present on the CAP pin.
The minimum usable value is 200pF, placed close to
the pins. A 0.01uF, 16V capacitor is recommended.
See
Figure 3
and
Figure 4
for variation of switch on/off
times vs. capacitance.
