Description
The PI5A121/PI5A122/PI5A124 are analog switches designed
for single-supply operation. These high-precision devices are
ideal for low-distortion audio, video, signal switching and rout-
ing.
The PI5A121 is a single-pole throw (SPST) normally open (NO)
switch. The switch is open when IN is LOW. The PI5A122 is
a single-pole single-throw (SPST) 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 <10Ω On-Resistance. On-Resistance
matching between channels is within 2Ω. On-Resistance flatness
is less than 55Ω over the specified range. These switches also
guarantee fast switching speeds (tON <20ns).
These products are available in 5-pin SC70 and/or 6-pin SOT23
plastic packages for operation over the industrial (-40oC to +85oC)
temperature range.
