Asynchonous Reset (RS) Input
Description
The PS395A eight-channel, serially controlled, single-pole/single-
throw (SPST) analog switch offers eight separately controlled
switches that conduct equally well in either direction. ON-resis-
tance (35-ohms max.) is matched between switches to 2-ohms max.
and is flat (4-ohms max.) over the specified signal range.
These CMOS devices can operate continuously with dual power
supplies ranging from 鹵2.7V to 鹵8V or a single supply between
+2.7V and +16V. Each switch can handle rail-to-rail analog signals.
Upon power-up, all switches are off, and the internal shift registers
are reset to zero. The PS395A is electrically equivalent to two PS391
quad switches controlled by a serial interface.
The serial interface is compatible with SPI聶/QSPI聶 and
Microwire聶. Functioning as a shift register, it allows data (at DIN)
to be clocked-in synchronously with the rising edge of clock
(SCLK). The shift register聮s output (DOUT) enables devices to be
daisy chained.
All digital inputs have 0.8V to 2.4V logic thresholds, ensuring both
TTL- and CMOS-logic compatibility when using 鹵5V supplies or a
single +5V supply.

NO and COM pins are identical and interchangeble. Either may be
considered as an input or an output; signals pass equally well in
either direction.
