Description
The PI5A125 is a single analog switch designed for single-supply
operation. This high-precision device is ideal for low-distortion
audio, 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 when
on. When off, it blocks voltages up toV
CC
.
The PI5A125 is fully specified with +5V, and +3.3V supplies. With
+5V, it guarantees <10-ohms ON-resistance. ON-resistance flatness
is less than 5-ohms over the specified range. The switch also
guarantees fast switching speeds (t
ON
<20ns).
This product is available in a 5-pin SOT23 plastic package for
operation over the industrial (–40°C to +85°C) temperature range.
