MAX395 Maxim, MAX395 Datasheet - Page 8

• Manufacturer Part Number: MAX395
• Description: The MAX395 8-channel, serially controlled, single-pole/single-throw (SPST) analog switch offers eight separately controlled switches
• Manufacturer: Maxim

Serially Controlled, Low-Voltage,
8-Channel SPST Switch
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.
