Note 5: On-resistance flatness is defined as the difference between the maximum and minimum on-resistance values, as measured
over the specified analog signal range.
Note 6: Leakage parameters are 100% tested at maximum rated temperature, and guaranteed by correlation at T

Note 8: All timing is measured from the clock’s falling edge preceding the ACK signal for 2-wire, and from CS’s rising edge for
3-wire. Turn-Off Time is defined as the output of the switch for 0.5V change, tested with a 300Ω load to ground. Turn-On
Time is measured with a 5kΩ load resistor to GND. All timing is shown with respect to 20% of V+ and 70% of V+, unless
otherwise noted.
Note 9: Typical values are for MAX4570 only.
Note 10: Supply current can be as high as 2mA per switch during switch transitions in the clickless mode, corresponding to 40mA
total supply transient current requirement.
Note 11: Leakage testing for single-supply operation is guaranteed by testing with dual supplies.
Note 12: Cb = capacitance of one bus line in pF. Tested with Cb = 400pF.
