CTR-SYNC
Synchronous binary counter
Updates its binary count from a common clock with the documented count-enable, load and clear controls.

Ripple binary counter
Counts clock events through cascaded storage stages whose output changes do not occur simultaneously.

What it represents
Counts clock events through cascaded storage stages whose output changes do not occur simultaneously.
On a schematic, identify the count input, clock polarity and clear input and trace the binary outputs and any decoded control signals. Keep the component tag and signal/reference names consistent across the control drawing, terminal schedule and device documentation.
Ripple transitions can briefly expose intermediate combinations; synchronous counters have a different update arrangement.
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 count input, clock polarity and clear input.
- Trace the binary outputs and any decoded control signals.
Information to show or reference
- Label the count input, clock polarity and clear input.
- Cross-reference the binary outputs and any decoded control signals.
- Add the selected device or circuit documentation revision, power/reference connections and project signal convention.
A distinction that matters
Ripple transitions can briefly expose intermediate combinations; synchronous counters have a different update arrangement.
