FSA66 Low Voltage UHS Single SPST Normally Open Analog Switch
November 2002 Revised August 2003
FSA66 Low Voltage UHS Single SPST Normally Open Analog Switch
General Description
The FSA66 is a ultra high-speed (UHS) CMOS compatible single-pole/single-throw (SPST) analog switch. The LOW On Resistance of the switch allows input to be connected to output with minimal propagation delay and without generating additional ground bounce noise. The device is organized as a 1-bit switch with a switch enable (OE) signal. When OE is HIGH, the switch is on and Port A is connected to Port B. When OE is LOW, the switch is open and a high-impedance state exists between the two ports.

Note 1: The "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The "Recommended Operating Conditions" table will define the conditions for actual device operation. Note 2: The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed. Note 3: Unused inputs must be held HIGH or LOW. They may not float.

Note 4: Measured by the voltage drop between 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) pins. Note 5: All typical values are at the specified VCC, and TA = 25C. Note 6: Parameter is characterized but not tested in production. 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: All typical values are at the specified VCC, and TA = 25C. Note 9: This parameter is guaranteed by design but is not tested. The switch contributes no propagation delay other than the RC delay of the typical On Resistance of the switch and the 50 pF load capacitance, when driven by an ideal voltage source (zero output impedance). Note 10: Guaranteed by design. Note 11: Off Isolation = 20 log10 [VA/VBN].
