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: ∆RON = RON(MAX) - RON(MIN).
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 TA = +25°C.
Note 7: Off-isolation = 20 log (VCOM_ / VNO_ _ ), VCOM_ = output, VNO_ _ = input to off switch.
Note 8: All timing is measured from the clock’s falling edge preceding the ACK signal 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 defined at the output of the switch for a 0.5V change and measured 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 12mA
total supply transient current requirement.
Note 10: Leakage testing is guaranteed by testing with a +5.25V supply.
Note 11: Cb = capacitance of one bus line in pF. Tested with Cb = 400pF.
Note 12: Typical values are for MAX4563 devices.
(V+ = +5V, TA = +25°C, unless otherwise noted.)
