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.

Data Sheet - Detailed Description  
8 Detailed Description  
The AS1741/AS1742/AS1743 are low ON-resistance, low-voltage, dual analog SPST switches that operate from a sin-  
gle +1.6 to +3.6V supply.  
CMOS process technology allows switching of analog signals that are within the supply voltage range (GND to V+).  
ON Resistance  
When powered from a +3V supply, the AS1741/AS1742/AS1743 low (0.8Ω, max) ON-resistance allows high-speed,  
continuous signals to be switched in a variety of applications. All devices have very low RON flatness (0.18Ω, max) so  
they can meet or exceed the low-distortion audio requirements of modern portable audio devices.  
Bi-Directional Switching  
Pins NOx, NCx, and COMx are bi-directional and can be used as inputs or outputs.  
Analog Signal Levels  
Analog signals ranging over the entire supply voltage range (V+ to GND) can be passed with very little change in ON-  
resistance (see Typical Operating Characteristics on page 6).  
Logic Inputs  
The AS1741/AS1742/AS1743 logic inputs can be driven up to +3.6V regardless of the supply voltage value. For exam-  
ple, with a +1.8V supply, INx may be driven low to GND and high to +3.6V. This allows the devices to interface with  
+3V systems using a supply of less than 3V.

AS1741  
Data Sheet - Application Information  
9 Application Information  
Power Supply Sequencing  
Proper power-supply sequencing is critical for proper switch operation. The power supplies should be started up in the  
following sequence:  
1. V+  
2. NOx, NCx, COMx  
Note: Operation beyond the absolute maximum ratings (see page 2) may permanently damage the devices.  
Power Supply Bypass  
Power supply connections to the devices must maintain a low impedance to ground. This can be done using a bypass  
capacitor, which will also improve noise margin and prevent switching noise propagation from the V+ supply to other  
components.  
A 0.1µF bypass capacitor, connected from V+ to GND (see Figure 17 on page 11), is adequate for most applications.  
Logic Inputs  
Driving INx Rail-to-Rail will help minimize power consumption.  
Layout Considerations  
High-speed switches require proper layout and design procedures for optimum performance.  
Short, wide traces should be used to reduce stray inductance and capacitance.  
Bypass capacitors should be as close to the device as possible.  
Large ground planes should be used wherever possible.

Notes:  
1. Measurements are standardized against short-circuit at socket terminals.  
2. Off-isolation is measured between COMx and the off NCx/NOx terminal of each switch. Off-isolation = 20log(VOUT/VIN).  
3. Signal direction through the switch is reversed; worst values are recorded.
