1 General Description
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
.
The AS1743 supports break-before-make switching.
With very low ON-resistance (R
ON
), R
ON
matching, and
R
ON
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.

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.
Signals on pins COM1, COM2, NO1, NO2, NC1, or NC2 that exceed V+ or GND are clamped by internal diodes.
Limit forward-diode current to the maximum current rating.

ON Resistance
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 (0.8
, max) ON-resistance allows high-speed,
continuous signals to be switched in a variety of applications. All devices have very low R
ON
flatness (0.18
, 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 5
).
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.

Power Supply Sequencing
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 0.1F 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.

Figure 17. Off-Isolation, On-Loss, and Crosstalk
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(V

).
3. Signal direction through the switch is reversed; worst values are recorded.
