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
Ω
, 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
Ω
, max) so
they can meet or exceed the low-distortion audio requirements of modern portable audio devices.
Bi-Directional Switching
Pins NO
x
, NC
x
, and COM
x
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, IN
x
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.
