Description
The PI5A100 is an improved Quad Single-pole double-throw
(4SPDT) CMOS analog switch designed to operate with a single
+2V to +6V power supply. The EN pin may be used to place all
switches in a high-impedance state. This high precision device
is ideal for low-distortion audio, video, and data switching and
routing.
Each switch conducts current equally well in either direction
when on. In the off state each switch blocks voltages up to the
power-supply rails.
The PI5A100 is fully specified with +5V, and +3.3V supplies. With
+5V, it guarantees less than 10Ω On-Resistance. On-Resistance
matching between channels is within 2Ω. On-Resistance flatness
is less than 4Ω over the specified range. The PI5A100 guarantees
fast switching speeds (t
ON
< 12ns).
The PI5A100 is available in the narrow-body SOIC and QSOP
packages for operation over the industrial (-40°C to +85°C) tem-
perature range.
Applications
• Audio, Video Switching and Routing
