Buffers, Drivers, Receivers, Transceivers

Logic buffers, drivers, receivers and transceivers allow isolated access to logic signals from one circuit for use in another circuit. Buffers pass their input signal, either unchanged or inverted, to their output and may be used to clean up a weak signal or drive a load. In a boolean logic simulator, a buffer is mainly used to increase propagation delay. Logic receivers and transceivers allow isolated communication between data buses.
