General Description
FSA4157 and FSA4157A are high performance Single
Pole/Double Throw (SPDT) analog switches. Both devices
feature ultra low R
will operate over the wide V
FSA4157, and 2.7V to 5.5V for FSA4157A. The device 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 FSA4157A features very low quiescent current even
when the control voltage is lower than the V
feature services the mobile handset applications very well
allowing for the direct interface with baseband processor
general purpose I/Os.
