DESCRIPTION
The RS2105 is a dual, low on-resistance, single-pole
double-throw (SPDT) analog switch that is designed to
operate from1.8 V to 5.5 V.
The RS2105 device can handle both analog and digital
signals. It features fast switching speeds (50ns) and
low on-resistance (0.6Ω TYP).
Applications include signal gating, chopping,
modulation or demodulation (modem), and signal
multiplexing for analog-to-digital and digital-to-analog
conversion systems.

(1) Stresses above these ratings may cause permanent damage. Exposure
to absolute maximum conditions for extended periods may degrade
device reliability. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those
specified is not implied.
(2) Input terminals are diode-clamped to the power-supply rails. Input
signals that can swing more than 0.3V beyond the supply rails should
be current-limited to 10mA or less.

ESD damage can range from subtle performance
degradation to complete device failure. Precision
integrated circuits may be more susceptible to
damage because very small parametric changes
could cause the device not to meet its published
specifications.
