What it represents
For two positive-logic inputs, produces a true output when the input states differ.
On a schematic, identify the two compared digital states and trace the inequality output and its control or monitoring use. Keep the component tag and signal/reference names consistent across the control drawing, terminal schedule and device documentation.
Two-input XOR is not inclusive OR; for more inputs verify whether the device implements odd parity or another specified function.
Terminal letters describe electrical roles, not package pin numbers. Check the selected public datasheet for the actual pin assignment, polarity and any internally connected terminals before completing the drawing.
How to read it
- Identify the two compared digital states.
- Trace the inequality output and its control or monitoring use.
Information to show or reference
- Label the two compared digital states.
- Cross-reference the inequality output and its control or monitoring use.
- Add the selected device or circuit documentation revision, power/reference connections and project signal convention.
A distinction that matters
Two-input XOR is not inclusive OR; for more inputs verify whether the device implements odd parity or another specified function.
