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. Standard Products
The AS1743 supports break-before-make switching.
With very low ON-resistance (R
R
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.
