PS395
Precision8-Channel17V,
SPSTSwitchw/SerialControl
Addressable Serial Interface
When several serial devices are configured as slaves, addressable
by the processor, DIN pins of each decode logic individually con-
trol CS of each slave device. When a slave is selected, its CS pin is
driven low, data is shifted in, and CS is driven high to latch the
data. Typically, only one slave is addressed at a time. DOUT is not
used.
Applications Information
Multiplexers
The PS395 can be used as a multiplexer.
Single Supply
The PS395 operates from a single supply between +3V and +16V
when V- is connected to GND. All of the bipolar precautions must
be observed.

High-Frequency Performance
In 50 systems, signal response is reasonably flat up to 50 MHz
(see Typical Operating Characteristics). Above 20 MHz, the on-
response has several minor peaks that are highly layout depen-
dent. The problem is not turning the switch on, but turning it
off. The off-state switch acts like a capacitor and passes higher
frequencies with less attenuation. At 10MHz, off isolation is about
45dB in 50 systems, becoming worse (approximately 20dB per
decade) as frequency increases. Higher circuit impedances also
make off isolation worse. Adjacent channel attenuation is about
3dB above that of a bare IC socket, and is due entirely to capaci-
tive coupling.
