WebbAn open collector output refers to an output that is connected to the collector of a transistor. Basically, just think of a transistor. A BJT transistor has a base, a collector, and an emitter. An open collector … Webb1 mars 2012 · The emitter of the transistor is connected to ground and the collector of the transistor is connected to the output. This is the “open collector.”. When a logical input to the SN7407N is low, the output of the NOT gate is high, so the base of the transistor is held at a voltage above the emitter. This “turns on” the transistor, which ...

WebbOpen Collector (“OC”) outputs are low powered, solid state switches. Although the term “Open Collector” stipulates the use of bipolar transistors (NPN-type or PNP-type) as a switch, nowadays Field Effect Transistors (FET or MOSFET) are used. WebbThe Open-Collector Output is a transistor circuit configuration used in a wide variety of electronic designs includ- ing many integrated circuits (ICs). Three parts make up a … Webboutput is low if the chip’s output voltage is below a certain percentage of its nominal value.
