FSA66 Low-Voltage UHS Single SPST Normally Open Analog Switch
June 2006
FSA66 Low-Voltage UHS Single SPST Normally Open Analog Switch
Features
Space-saving SOT23 or SC70 5-lead package Ultra small MicroPakTM leadless package Broad VCC operating range: 1.65V-5.5V Rail-to-rail signal handling 5 switch connection between two ports Minimal propagation delay through the switch Low ICC Zero bounce in flow-through mode Control input compatible with CMOS input levels >250 MHz -3dB bandwidth
General Description
The FSA66 is a ultra high-speed (UHS) CMOS compatible Single-Pole/Single-Throw (SPST) analog switch. The low On Resistance (RON) 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.

Absolute Maximum Ratings
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 defines the conditions for actual device operation.

Notes: 3. 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. 4. All typical values are at the specified VCC, and TA = 25C. 5. Parameter is characterized, but not tested in production. 6. Flatness is defined as the difference between the maximum and minimum value of on resistance over the specified range of conditions.
