FSA66 Low-Voltage UHS Single SPST Normally Open Analog Switch
FSA66 Rev. 1.0.1
DC Electrical Characteristics
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.
