Circuit operation is easily illustrated by its response to a discrete pulse. If the input is low for a long time, pin 4 of the XOR gate is low but pin 5 is high, due to signal inversion by the ...

requires a control circuit that interfaces with the ... monitor and network. Audio output may comprise a single 3.5mm Line Out port or multiple ports for surround sound (see PC audio ports).

When the switch is OFF, the diagnostic status indicates the presence of load open-circuit fault. Figure 1b shows how to connect a low-side digital input (S2) to an output pin of the L9822.

To further enhance stability, both optical isolators are located inside the same IC. Both the input and output circuits operate from single power supplies (one for the input side and a 2nd for the ...
