1 General Description
The AS1751/AS1752/AS1753 are high-speed, low-voltage, quad single-pole/single-throw (SPST) analog switches. Fast switching speeds, low ON-resistance, and low power consumption make these devices ideal for singlecell 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. Figure 1. 14-pin TSSOP Block Diagrams AS1751
