8 Detailed Description
The AS1744/AS1745 are low ON-resistance, low-voltage, dual analog SPDT switches that operate from a single +1.8
to +5.5V 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 +5V supply, the low R
ON
(4
Ω
max) allows high continuous currents to be switched in a wide
range of applications. All devices have low R
ON
flatness (1
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, thus they can be used as inputs or outputs.
Analog Signal Levels
Analog signals ranging over the entire supply voltage (V+ to GND) can be passed with very little change in ON-resis-
tance (see
Typical Operating Characteristics on page 6
).
Logic Inputs
The AS1744/AS1745 logic inputs (IN
x
) can be driven up to +5.5V regardless of the supply voltage value. For example,
with a +3.3V supply, IN+ may be driven low to GND and high to +5.5V. This allows the devices to interface with +5V
systems using a supply of less than 5V.
