PI5A125 General Description

The PI5A125 is a single analog switch designed for single-supplyoperation. This high-precision device is ideal for low-distortionaudio, video, signal switching and routing.

The PI5A125 is a single-pole single-throw (SPST), normally closed(NC) switch. The switch is open when OE is HIGH.

This switch conducts current equally well in either direction whenon. When off, it blocks voltages up toVCC.

The PI5A125 is fully specified with +5V, and +3.3V supplies. With+5V, it guarantees <10-ohms ON-resistance. ON-resistance flatnessis less than 5-ohms over the specified range. The switch alsoguarantees fast switching speeds (tON <20ns).

This product is available in a 5-pin SOT23 plastic package foroperation over the industrial (40°C to +85°C) temperature range.

PI5A126 General Description

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 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 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 products are available in 8-pin SOIC and MSOP plasticpackages for operation over the industrial temperature range(40oC to +85oC).
