PARAMETER
The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.
Guaranteed by design. Not subject to production testing.
∆R
Resistance flatness is defined as the difference between the maximum and minimum on-resistance values, as measured
over the specified analog signal range.
Leakage parameters are 100% tested at maximum rated temperature and guaranteed by correlation at T
Off-isolation = 20log (V
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.
Supply current can be as high as 2mA per switch during switch transitions in the clickless mode, corresponding to a 48mA
total supply transient current requirement.
