Description
The FSA2267 and FSA2267A are Dual Single Pole Double Throw (SPDT) analog switches. The FSA2267 operates from a single 1.65V to 3.6V supply, while the FSA2267A operates from a single 2.3V to 4.3V supply. Each features an ultra-low On Resistance of 0.35 at a +2.7V supply and 25°C. Both devices are fabricated with sub-micron CMOS technology to achieve fast switching speeds and designed for break-before-make operation.
FSA2267A features very low quiescent current, even when the control voltage is lower than the VCC supply. This feature services the mobile handset applications very well, allowing for the direct interface with baseband processor general-purpose I/Os.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only..
