ELM415 interface equivalent, up/down interface.
* Low power CMOS design
* Wide supply range
– 3.0 to 5.5 volts
* Fully debounced switch inputs
* Internal pullup resistors provided
* .
* Digital audio potentiometer controls
* Variable voltage or temperature circuits
* Motor positioning contro.
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 .
