December 2002 Revised December 2002
FSA3357 Low Voltage SP3T Analog Switch (3:1 Multiplexer/Demultiplexer)
General Description
The FSA3357 is a high performance, single-pole/triplethrow (SP3T) Analog Switch or 3:1 Multiplexer/Demultiplexer. The device is fabricated with advanced sub-micron CMOS technology to achieve high speed enable and disable 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 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.
Features
s Useful in both analog and digital applications s Space saving US8 8-lead surface mount package s Low On Resistance; < 9 on 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 specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. Fairchild does not recommend operation outside datasheet specifications. 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.

OFF State Leakage Current 1.65 - 5.5
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.

Note 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 50 pF load capacitance, when driven by an ideal voltage source (zero output impedance). Note 9: Guaranteed by Design. Note 10: Off Isolation = 20 log10 [VA / VBn]
