Notes:
3.
Guaranteed, but not tested for VCC=1.65 V.
4.
On resistance is determined by the voltage drop between A and B pins at the indicated current through the switch.
5.
RON=RON max – RON min measured at identical VCC, temperature, and voltage.
6.
Flatness is defined as the difference between the maximum and minimum value of on resistance (RON) over the
specified range of conditions.
