Data Sheet
The AS1751/AS1752/AS1753 are high-speed, low-volt-
age, quad single-pole/single-throw (SPST) 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 single +1.6
to +3.6V supply, and are differentiated by the type and
number of switches:
!
AS1751 – Four normally open (NO) switches
!
AS1752 – Four normally closed (NC) switches
!
AS1753 – Two NO switches and Two NC switches
The AS1753 supports break-before-make switching.
With very 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 AS1751/AS1752/AS1753 digital logic input is 1.8V
CMOS-compatible when using a +3V supply, and all
devices can handle Rail-to-Rail signals.
The devices are available in a 3mm x 3mm 16-pin TQFN
package and a 14-pin TSSOP 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,
hard drives, and any other application where high-speed
signal switching is required.
