1 General Description

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 (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 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.

players, PDAs, handheld computers, digital cameras,

hard drives, and any other application where high-speed

signal switching is required.
