Serially Controlled, Low-Voltage,

8-Channel SPST Switch

_______________________________________________________________________________________

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.

TIMING CHARACTERISTICS—Single +3V Supply (Figure 1)

(V+ = +3.0V to +3.6V, V- = 0V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)
