Data Sheet
1 General Description
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 (RON), RON matching, and RON
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.

3 Applications
The devices are ideal for use in power routing systems,
cordless and mobile phones, MP3 players, CD and DVD
players, PDAs, handheld computers, digital cameras,
and any other application where high-speed signal
switching is required.

4 Absolute Maximum Ratings
Stresses beyond those listed in Table 1 may cause permanent damage to the device. These are stress ratings only,
and functional operation of the device at these or any other conditions beyond those indicated in Section 5 Electrical
Characteristics on page 3 is not implied. Exposure to absolute maximum rating conditions for extended periods may
affect device reliability.
