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

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

What it represents
Updates its binary count from a common clock with the documented count-enable, load and clear controls.
On a schematic, identify the common clock, enables, load data and reset timing and trace the count outputs and carry/cascade signal. Keep the component tag and signal/reference names consistent across the control drawing, terminal schedule and device documentation.
Synchronous operation does not remove setup/hold and output-delay requirements; reset can be synchronous or asynchronous depending on the part.
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 common clock, enables, load data and reset timing.
- Trace the count outputs and carry/cascade signal.
Information to show or reference
- Label the common clock, enables, load data and reset timing.
- Cross-reference the count outputs and carry/cascade signal.
- Add the selected device or circuit documentation revision, power/reference connections and project signal convention.
A distinction that matters
Synchronous operation does not remove setup/hold and output-delay requirements; reset can be synchronous or asynchronous depending on the part.
