General Description
The FSA66 is a ultra high-speed (UHS) CMOS compati-
ble Single-Pole/Single-Throw (SPST) analog switch. The
low On Resistance (R
ON
) 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 V
CC
, and T
A
= 25°C.
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.

8. 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).
