Note 2: The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.

Note 3: Guaranteed by design. Not subject to production testing.

Note 4:

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 7: Off-isolation = 20

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 300

Ω load to ground. Turn-On

Time is measured with a 5k

Ω 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.
