Dual SPST Analog Switches
1 General Description
2 Key Features
Data Sheet
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.
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
Switch Types
AS1741
Two Normally Open (NO) Switches
AS1742
Two Normally Closed (NC) Switches
AS1743
One NO Switch and One NC Switch
The AS1743 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 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.
The devices are available in an 8-pin MSOP package
and an 8-pin SOT23 package.
! ON-Resistance:
- 0.8(+3V supply)
- 2.5(+1.8V supply)
! RON Matching: 0.08(+3V supply)
! RON Flatness: 0.18(+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
! 1.8V CMOS Logic Compatible (+3V supply)
! Total Harmonic Distortion: 0.03%
! Operating Temperature Range: -40 to +85ºC
! Package Types:
- 8-pin MSOP
- 8-pin SOT23
3 Applications
Figure 1. MSOP Block Diagrams
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.

4 Absolute Maximum Ratings
Stresses beyond those listed in Table 2 may cause permanent damage to the device. These are stress ratings only,
and functional operation of the device at these or any other conditions beyond those indicated in Section 5 Electrical
Characteristics on page 3 is not implied. Exposure to absolute maximum rating conditions for extended periods may
affect device reliability.
