Note 2:

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 = 20log (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 300

Ω load to ground. Turn-on

time is defined at the output of the switch for a 0.5V change and measured with a 5k

Ω load resistor to GND. All timing is

shown with respect to 20% V+ and 70% V+, unless otherwise noted.

Note 9:

Typical values are for MAX4586 devices.

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.
