Description
The PI5A127 is a dual SPST (single-pole single-throw) analog
switches designed for single supply operation.
These high-precision devices are ideal for low-distortion audio,
video, signal switching and routing.
The PI5A127 is a normally closed (NC) switch.
Each switch conducts current equally well in either direction
when on. When off, they block voltages up to V+.
These switches are fully specified with +5V and +3.3V supplies.
With +5V, they guarantee <10 -ohm ON-resistance. On-resistance
matching between channels is within 2-ohm. On-resistance flatness
is less than 5-ohm over the specified range. These switches also
guarantee fast switching speeds (t
ON
< 20ns).
These products are available in 8-pin SOIC and MSOP plastic
packages for operation over the industrial temperature range
(–40
o
C to +85
o
C).

clamped by internal diodes. Limit forward diode current to 30mA.
Caution:
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating
and operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied.
