TIMING CHARACTERISTICS—Dual Supplies (Figure 1)
(V+ = +4.5V to +5.5V, V- = -4.5V to -5.5V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)
Note 1: The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.
Note 2:
RON = RON(max) - RON(min). On-resistance match between channels and on-resistance flatness are guaranteed only with
specified voltages. Flatness is defined as the difference between the maximum and minimum value of on-resistance as
measured over the specified analog signal range.
Note 3: Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at room temp.
Note 4: Guaranteed by design.
Note 5: Leakage testing at single supply is guaranteed by testing with dual supplies.
Note 6: See Figure 6. Off-isolation = 20log10 VCOM/VNO, VCOM = output. NO = input to off switch.
Note 7: Between any two switches. See Figure 3.
