MAX350 Maxim, MAX350 Datasheet - Page 10

• Manufacturer Part Number: MAX350
• Description: The MAX349/MAX350 are 8-channel and dual 4-channel serially controlled multiplexers (muxes)
• Manufacturer: Maxim

TIMING CHARACTERISTICS—Single +3V Supply (Figure 1)
(V+ = +3.0V to +3.6V, V- = 0V, T

Note 1: The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.
Note 2: ∆R
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 = 20log
Note 7: Between any two switches. See Figure 3.
