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 routing. The is a single-pole throw (SPST) normally open (NO) switch. The switch is open when IN is LOW. The 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 <10-ohm ON-resistance. ON-resistance matching between channels is within 2ohms. ON-resistance flatness is less than 5ohms over the specified range. These switches also guarantee fast switching speeds (tON <20ns). These products are available 5-pin SC70 and/or 6-pin SOT23 plastic packages for operation over the industrial to +85oC) temperature range.
