• Manufacturer Part Number: MAX349-MAX350
• Description: Serially Controlled, Low-Voltage, 8-Channel/Dual 4-Channel Multiplexers
• Manufacturer: MAXIM [Maxim Integrated Products]

TIMING CHARACTERISTICS—Single +5V Supply (Figure 1)
(V+ = +4.5V to +5.5V, 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.
