Descriptions
The DIO1269
is a high-performance, dual
Single-Pole Double-Throw (SPDT) analog switch
with negative swing audio capability. The DIO1269
features ultra-low RON of 1Ω (typical) at 3.0V VCC.
The DIO1269 operates over a wide VCC range of
2.7V to 5V, is fabricated with sub-micron CMOS
technology to achieve fast switching speeds, and
is designed for break-before-make operation. The
select input is TTL-level compatible.
The DIO1269 features very low quiescent current
even when the control voltage is lower than the
VCC supply. This feature suits mobile handset
applications by allowing direct interface with
baseband processor general-purpose I/Os with
minimal battery consumption.

Absolute Maximum Ratings
DIO1269
Stresses beyond those listed under “Absolute Maximum Rating” may cause permanent damage to the device. These are stress
ratings only and functional operation of the device at these or any other condition beyond those indicated in the operational sections
of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
