Description
The PI5A319A is an analog switch designed for single-supply
operation. It is ideal for low-distortion audio, video, signal switch-
ing and routing.
The PI5A319A is a single-pole, double-throw (SPDT) switch. The
switch conducts current equally well in either direction when on.
When off, they block voltages up toVCC.
The PI5A319A is fully specified with +5V and +3.3V supplies.
With +5V, they guarantee <18-ohm On-Resistance.
On-Resistance matching between channels is within 2-ohm.
On-Resistance flatness is less than 5-ohm over the specified range.
This switch family also guarantees fast switching speeds (tON < 20ns).
The device is available in a 8-pin narrow body SOIC package for
operation over the industrial (-40oC to +85 oC) temperature range.
