Digital Constant Logic-Level Source

Application

This circuit shows a digital constant used as a fixed logic source for a control input or test point.

Schematic Organization

The featured source is on the left. Its output runs to a digital probe and a light 10K load on the right, with one ground reference for the load return.

Expected Behavior

With STATE set to 1, OUT should read as logic high. Setting STATE to 0 should drive the same node low.

Suggested Experiments

Change STATE between 1 and 0, or change VHIGH from 5 to 3.3, then rerun the transient simulation and compare the digital output.

Featured Component

The featured component provides a configurable logic state and output levels while preserving the one-pin source shape used by imported schematics.
