Description
FSA4157 and FSA4157A are high performance Single
Pole/Double Throw (SPDT) analog switches. Both
devices feature ultra low RON of 1.15Ω maximum at
4.5V VCC and will operate over the wide VCC range of
1.65V to 5.5V for 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.
Break-Before-Make Enable Circuitry
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.
Over-Voltage Tolerant TTL-Compatible Control
Circuitry
Technology Description
Fast Turn-On and Turn-Off Time
The Fairchild Switch family derives from and embodies
Fairchild’s proven switch technology used for several
years in its 74LVXL384 (FST3384) bus switch product.

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.

Notes:
4. Measured by the voltage drop between the A and B pins at the indicated current through the switch. On
resistance is determined by the lower of the voltage on the two (A or B ports).
5. ΔRON = RON max – RON min measured at identical VCC, temperature, and voltage.
6. Flatness is defined as the difference between the maximum and minimum value of on resistance over the
specified range of conditions.
