The PI5A317A/381A/319A are analog switches designed for single-
supply operation. These high-precision device is ideal for low-
distortion audio, video, signal switching and routing.
The PI5A317A is a single-pole single-throw (SPST), normally
closed (NC) switch. The PI5A318A has the same pinout but is a
single-pole, single-throw (SPST, normally open (NO) function. The
PI5A319A is a single-pole, double-throw (SPDT) switch
Each switch conducts current equally well in either direction when
on. When off, they block voltages up toV
CC
.
The PI5A317A/381A/319A are fully specified with +5V and +3.3V
supplies. With +5V, they guarantee <18-ohm On-Resistance.
On-Resistance matching between channels is within 2-ohm.
On-Resistance flatness is less than 5-ohm over the specified range.
This switch family also guarantees fast switching speeds (t
ON
< 20ns).
These products are available in a 8-pin narrow body SOIC package
for operation over the industrial (-40
o
C to +85
o
C) temperature range.
