Digital magnitude comparator

What it represents

Compares two digital words to provide the specified equality and magnitude indications.

On a schematic, identify the two word buses, bit significance and cascade inputs and trace the equal, greater-than and less-than outputs. Keep the component tag and signal/reference names consistent across the control drawing, terminal schedule and device documentation.

Digital word comparison differs from an analogue voltage comparator, even though both can use a comparison block in a diagram.

The preview is an independently drawn educational functional reference. Add the selected component’s actual power pins, terminal numbers, timing or analogue reference details when producing a construction drawing.

How to read it

• Identify the two word buses, bit significance and cascade inputs.
• Trace the equal, greater-than and less-than outputs.

Information to show or reference

• Label the two word buses, bit significance and cascade inputs.
• Cross-reference the equal, greater-than and less-than outputs.
• Add the selected device or circuit documentation revision, power/reference connections and project signal convention.
