General Description

The ELM415 is an 8 pin device that simplifies the connections between a pushbutton type human interface and many counter-based circuits.

Counter circuits are often employed for such things as temperature control, audio volume control, level settings etc., but some require a direction and a step input, which are not intuitive for human operators.

With the ELM415, all you need do is provide two pushbuttons - one to increase the count, and one to decrease it.
