complementary output

Definition

The appropriate product category Rotary Encoders: An output circuit with two output transistors (NPN and PNP) on the output. These two output transistors alternately turn ON and OFF depending on the high or low output signal. The complementary output allows flow-in or flow-out of the output current and thus the rising and falling speeds of signals are fast. This allows a long cable distance. They can be connected to open-collector input devices (NPN or PNP).
