•
The TS3A24159 is a 2-channel single-pole doublethrow (SPDT) bidirectional analog switch that is
designed to operate from 1.65 V to 3.6 V. It
offers low ON-state resistance and excellent ONstate resistance matching with the break-beforemake feature, to prevent signal distortion during the
transferring of a signal from one channel to another.
The device has excellent total harmonic distortion
(THD) performance, low ON-state resistence, and
consumes very low power. These are some of the
features that make this device suitable for a variety of
markets and many different applications.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress
ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under
Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device
reliability.
The algebraic convention, whereby the most negative value is a minimum and the most positive value is a maximum.
All voltages are with respect to ground, unless otherwise specified.
This value is limited to 5.5 V maximum.
