AND
AND gate
A logic element whose output is true when all stated positive-logic inputs are true.

What it represents
Produces the opposite logical state of its defined digital input.
On a schematic, identify the input/output polarity and logic supply domain and trace the inverted signal and receiving-device interface. Keep the component tag and signal/reference names consistent across the control drawing, terminal schedule and device documentation.
A digital NOT gate inverts a logic state; an inverting analogue amplifier changes a continuous signal with a gain relationship.
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 input/output polarity and logic supply domain.
- Trace the inverted signal and receiving-device interface.
Information to show or reference
- Label the input/output polarity and logic supply domain.
- Cross-reference the inverted signal and receiving-device interface.
- Add the selected device or circuit documentation revision, power/reference connections and project signal convention.
A distinction that matters
A digital NOT gate inverts a logic state; an inverting analogue amplifier changes a continuous signal with a gain relationship.
