Description

The PI5A127 is a 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 PI5A127 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-ohm. On-resistance flatness

is less than 5-ohm 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

(–40oC to +85oC).
