Detailed Description
The MAX4719 high-speed, low-voltage, 20
R
ON
, dual
SPDT analog switch operates from a single +1.8V to
+5.5V supply. The switch features break-before-make
switching operation and fast switching speeds (t
ON
=
80ns (max), t
OFF
= 40ns (max)).
Applications Information
Digital Control Inputs
The MAX4719 logic inputs accept up to +5.5V regard-
less of supply voltage. For example, with a +3.3V sup-
ply, IN_ can be driven low to GND and high to +5.5V
allowing for mixing of logic levels in a system. Driving
the control logic inputs rail-to-rail minimizes power con-
sumption. For a +3V supply voltage, the logic thresh-
olds are 0.5V (low) and 1.4V (high); for a +5V supply
voltage, the logic thresholds are 0.8V (low) and 2.0V
(high).
Analog Signal Levels
The on-resistance of the MAX4719 changes very little for
analog input signals across the entire supply voltage
range (see the
Typical Operating Characteristics
). The
switches are bidirectional, so the NO_, NC_, and COM_
pins can be either inputs or outputs.
