CASE 127EB
Description
FSA4157 and FSA4157A are high performance Single Pole/Double
Throw (SPDT) analog switches. Both devices feature ultra low RON of
1.15 W maximum at 4.5 V VCC and operates over the wide VCC range
of 1.65 V to 5.5 V for FSA4157, and 2.7 V to 5.5 V 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 VCC supply. This feature services the
mobile handset applications very well allowing for the direct interface
with baseband processor general purpose I/Os.
