The PI5A126/PI5A127 are 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 is a normally open (NO) switch. The switch is open when IN is LOW. The 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 ohms. On-resistance flatness is less than 5 ohms over the specified range. These switches also guarantee fast switching speeds (tON < 20ns). These products are available in 8-pin SOIC and MSOP plastic packages for operation over the industrial temperature range to +85oC).
