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 5: 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
A
= +25°C.

_ _ = input to off switch.
Note 8: All timing is measured from the rising clock edge of the ACK bit for 2-wire, and from the rising edge of CS for 3-wire. Turn-
off time is defined at the output of the switch for a 0.5V change, tested with a 300Ω load to ground. Turn-on time is mea-
sured with a 5kΩ load resistor to GND. All timing is shown with respect to 20% V+ and 70% V+, unless otherwise noted.
Note 9: Supply current can be as high as 2mA per switch during switch transitions in the clickless mode, corresponding to a 28mA
total supply transient current requirement.
Note 10: Leakage testing for single-supply operation is guaranteed by testing with a single +5.25V supply.
Note 11: C
b
= capacitance of one bus line in pF. Tested with C
b
= 400pF.
Note 12: Typical values are for MAX4573/MAX4574 devices.
