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)

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 (t

These products are available in 5-pin SC70 and/or 6-pin SOT23

plastic packages for operation over the industrial (-40

temperature range.
