Timing Characteristics - Single +3V Supply
(V+ = ±3.0V to +3.6V, V = 0V, TA = TMIN to TMAX, unless otherwise noted. Typical values are TA = +25°C).

Notes:
1. The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.
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.
3. Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at room temp.
4. Guaranteed by design.
5. Leakage testing at single supply is guaranteed by testing with dual supplies.
6. See Figure 5. Off isolation = 20log10 VCOM/VNO, VCOM = output. NO = input to off switch.
7. Between any two switches. See Figure 2.
