DESCRIPTION
The RS2253 is a CMOS analog IC configured as
three single-pole/double-throw (SPDT) switches. This
CMOS device can operate from 2.5 V to 5.5 V.
The RS2253 device are digitally-controlled analog
switches. It has low on-resistance (48Ω TYP) and
very low off-leakage current (1nA TYP).
The RS2253 is available in Green SOIC-16, SSOP-
16, TSSOP-16 and QFN-3×3-16L packages. It
operates over an ambient temperature range of -40°
C
to +125°
C.

(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 SENSITIVITY CAUTION
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.
