Note
1:
Demand mode, CONT/DEMAND = LOW. Figure 8-2 timing diagram. CL = 100 pF.
2: Continuous mode, CONT/DEMAND = HIGH. Figure 8-4 timing diagram.
3: Digital inputs have CMOS logic levels and internal pull-up/pull-down resistors. For TTL compatibility, external pull-up
resistors to VDD are recommended.
