

The FSA3157B is a high-performance, Single-Pole /
Double-Throw (SPDT) analog switch or 2:1 multiplexer /
de-multiplexer bus switch.
Useful in Both Analog and Digital Applications
Ultra-Small, MicroPak™ Leadless Package
Low On Resistance: <10 Typical at 3.3V VCC
Broad VCC Operating Range: 1.65V to 5.5V
Rail-to-Rail Signal Handling
Power-Down, High-Impedance Control Input
Over-Voltage Tolerance of Control Input to 7.0V
Break-Before-Make Enable Circuitry
250MHz, 3dB Bandwidth
The device is fabricated with advanced sub-micron
CMOS technology to achieve high-speed enable and
disable times and low on resistance. The break-beforemake select circuitry prevents disruption of signals on
the B Port due to both switches temporarily being
enabled during select pin switching. The device is
specified to operate over the 1.65 to 5.5V VCC operating
range. The control input tolerates voltages up to 5.5V,
independent of the VCC operating range.

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.

Electrical Characteristics
Notes:
3. 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 voltages on the two (A or B Ports).
4. Parameter is characterized, but not tested in production.
5. RON = RON maximum – RON minimum measured at identical VCC, temperature, and voltage levels.
6. Flatness is defined as the difference between the maximum and minimum value of on resistance over the
specified range of conditions.
7. Guaranteed by design.

8. This parameter is guaranteed by design, but not tested. The bus switch contributes no propagation delay other
than the RC delay of the on resistance of the switch and the 50pF load capacitance when driven by an ideal
voltage source (zero output impedance).
