What it represents
Advances a decoded output sequence through the documented ten-state counter arrangement.
On a schematic, identify the clock, inhibit and reset controls and trace the decoded outputs and carry/cascade path. Keep the component tag and signal/reference names consistent across the control drawing, terminal schedule and device documentation.
Decoded decade outputs differ from a binary-coded ten-state word; the selected device's sequence table defines the actual mapping.
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 clock, inhibit and reset controls.
- Trace the decoded outputs and carry/cascade path.
Information to show or reference
- Label the clock, inhibit and reset controls.
- Cross-reference the decoded outputs and carry/cascade path.
- Add the selected device or circuit documentation revision, power/reference connections and project signal convention.
A distinction that matters
Decoded decade outputs differ from a binary-coded ten-state word; the selected device's sequence table defines the actual mapping.
