1.
Refer to Figure 4: Test circuit for leakage current (IOFF) on page 11
2.
Measured by voltage drop between channels at indicated current through the switch. ON resistance is determined by the
lower of the voltages.
3.
Flatness is defined as the difference between the RONMAX and RONMIN of ON resistance over the specified range.
4.
ΔR
ON measured at same VCC, temperature and voltage level.
