ELM415 Up/Down Interface 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. The IC will provide the pushbutton debouncing, direction translation, and the count (step) output generation, all with little more than having power provided to it.
