Up/Down Interface

Description Many modern control circuits use the value from a digital counter to directly determine a setting or position. Manipulating this value under computer control is not difficult, but when one has to interface with a human operator, several other factors must be considered. Human interf

ELM

Up/Down Interface

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 inpu ·Low power CMOS design\n·Wide supply range – 3.0 to 5.5 volts\n·Fully debounced switch inputs\n·Internal pullup resistors provided\n·Protection from simultaneous key presses\n·High current drive outputs\n·User selectable automatic repeat function\n·Selectable Count output polarity;
