open collector

This type of connection is also referred to as open collector.

Link uses a single wire in an open collector configuration.

It is an open collector signal, that may be pulled down by the connector or the drive.

The LM339 accomplishes this with an open collector output.

The heart of an I2L circuit is the common emitter open collector inverter.

An open collector is a common type of output found on many integrated circuits (IC).

Open collector circuits are therefore sometimes used to interface different families of devices that have different operating voltage levels.

SCSI-1 devices use open collector for electrical signaling.

This is most commonly seen in TTL logic using 7406 open collector logic.

Open collector, electrical interface.

The wired AND function below is achieved by using open collector TTL gates.

The hardware utilized are RS-485 transceivers wired for open collector operation through the use of a pullup and pulldown of the separate data lines.

Logic of this type is most frequently encountered with the collector resistor of the output transistor omitted, making an open collector output.

Instead of an emitter follower topology, low-dropout regulators utilize open collector or open drain topology.

This allows the designer to fabricate logic by connecting the open collector outputs of several logic gates together and providing a single external pull-up resistor.

The signals are standard TTL 0-5V, except the Rx Busy output, which is an open collector pulldown.

By tying the output of several open collectors together, the common line becomes a "wired AND" (positive-true logic) or "wired OR" (negative-true logic) gate.

The cards use open collector interfaces, where a card may pull a line to the low voltage level; the line is at the high voltage level (because of a pull-up resistor) if no card pulls it low.

The alternative to a push-pull output is a single switch that connects the load either to ground (called an open collector or open drain output) or to the power supply (called an open-emitter or open-source output).

The 7407 TTL device, an open collector buffer, simply outputs whatever it receives as input, but as an open collector device, the output is left effectively unconnected when outputting a "1".

A three-state logic device is unlike an open collector device, because it comprises transistors to source and sink current in both logic states, as well as a control to turn off both transistors and isolate the output.

Many automotive Hall effect sensors have a built-in internal NPN transistor with an open collector and grounded emitter, meaning that rather than a voltage being produced at the Hall sensor signal output wire, the transistor is turned on providing a circuit to ground through the signal output wire.
