Data Sheet  
AS1741, AS1742, AS1743  
High-Speed, Low-Voltage, Single-Supply, 0.8Ω,  
Dual SPST Analog Switches  
1 General Description  
2 Key Features  
ꢀ ON-Resistance:  
- 0.8Ω (+3V supply)  
- 2.5Ω (+1.8V supply)  
The AS1741/AS1742/AS1743 are high-speed, low-volt-  
age, dual 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.  
ꢀ RON Matching: 0.08Ω (+3V supply)  
ꢀ RON Flatness: 0.18Ω (+3V supply)  
ꢀ Supply Voltage Range: +1.6 to +3.6V  
ꢀ Switching Action: tON = 22ns, tOFF = 14ns  
ꢀ Current-Handling: 250mA Continuous  
ꢀ Break-Before-Make Switching (AS1743)  
ꢀ Rail-to-Rail Signal Handling  
These highly-reliable devices operate from a single +1.6  
to +3.6V supply, and are differentiated by the type and  
number of switches as listed in Table 1.  
Table 1. Standard Products  
Model  
AS1741  
AS1742  
AS1743  
Switch Types  
Two Normally Open (NO) Switches  
Two Normally Closed (NC) Switches  
One NO Switch and One NC Switch  
The AS1743 supports break-before-make switching.  
ꢀ 1.8V CMOS Logic Compatible (+3V supply)  
ꢀ Total Harmonic Distortion: 0.03%  
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.  
ꢀ Operating Temperature Range: -40 to +85ºC  
The AS1741/AS1742/AS1743 digital logic input is 1.8V  
CMOS-compatible when using a single +3V supply, and  
all devices can handle Rail-to-Rail signals.  
ꢀ Package Types:  
- 8-pin MSOP  
- 8-pin SOT23  
The devices are available in an 8-pin MSOP package  
and an 8-pin SOT23 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.
