FSA3357
Low Voltage SP3T Analog Switch
(3:1 Multiplexer/Demultiplexer)
General Description
The FSA3357 is a high performance, single-pole/triple-
throw (SP3T) Analog Switch or 3:1 Multiplexer/Demulti-
plexer. The device is fabricated with advanced sub-micron
CMOS technology to achieve high speed enable and dis-
able times and low On Resistance. The break before make
select circuitry prevents disruption of signals on the B0, B1,
or B2 Ports due to the switches temporarily being enabled
during select pin switching. The device is specified to oper-
ate 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.
Features
s Useful in both analog and digital applications
s Space saving US8 8-lead surface mount package
s Low On Resistance; < 9on typ @ 3.3V VCC
s Broad VCC operating range; 1.65V to 5.5V
s Rail-to-Rail signal handling
s Power down high impedance control input
s Overvoltage tolerance of control input to 7.0V
s Break before make enable circuitry
s 250 MHz - 3dB bandwidth

Note 1: Absolute maximum ratings are DC values beyond which the device
may be damaged or have its useful life impaired. The datasheet specifica-
tions should be met, without exception, to ensure that the system design is
reliable over its power supply, temperature, and output/input loading vari-
ables. Fairchild does not recommend operation outside datasheet specifi-
cations.
Note 2: The input and output negative voltage ratings may be exceeded if
the input and output diode current ratings are observed.
Note 3: Control inputs must be held HIGH or LOW, they must not float.

Note 4: Measured by the voltage drop between A and Bn pins at the indicated current through the switch. On Resistance is determined by the lower of the
voltages on the two (A or Bn Ports).
Note 5: Parameter is characterized but not tested in production.
Note 6: RON = RON max RON min measured at identical VCC, temperature and voltage levels.
Note 7: Flatness is defined as the difference between the maximum and minimum value of On Resistance over the specified range of conditions.
