Data Sheet
The AS1744/AS1745 are high-speed, low-voltage, dual
single-pole/double-throw (SPDT) analog switches.
Fast switching speeds, low ON-resistance, and low
power-consumption make these devices ideal for single-
cell battery powered applications.
These highly-reliable devices operate from a +1.8 to
+5.5V supply, are differentiated by inverted logic, and
support break-before-make switching.
With low ON-resistance (R
ON
), R
ON
matching, and R
ON
flatness, the devices can accurately switch signals for
sample and hold circuits, digital filters, and op-amp gain
switching networks.
The devices are available in a 10-pin MSOP package
and a 10-pin TDFN package.
