These high-precision devices are ideal for low-distortion audio, video, signal switching and routing. 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 (t ON <20ns). These products are available in 5-pin SC70 and/or 6-pin SOT23 plastic packages for operation over the industrial (-40o C to +85o C) temperature range.
