DescriptionThe PI5A126/PI5A127 are dual SPST (single-pole single-throw)analog switches designed for single supply operation.
These PI5A126/PI5A127 high-precision devices are ideal for low-distortion audio,video, signal switching and routing. The PI5A126 is a normally open (NO) switch. The switch is openwhen IN is LOW. The PI5A127 is a normally closed (NC) switch. Each switch conducts current equally well in either directionwhen on. When off, they block voltages up to V+.
These PI5A126/PI5A127 switches are fully specified with +5V and +3.3V supplies. With +5V, they guarantee <10 -ohm ON-resistance. On-resistancematching between channels is within 2 ohms. On-resistance flatnessis less than 5 ohms over the specified range. These switchesalso guarantee fast switching speeds (tON < 20ns).
These PI5A126/PI5A127 are available in 8-pin SOIC and MSOP plasticpackages for operation over the industrial temperature range(40oC to +85oC).
