ELM411 Debounce Circuit with Latch
Description
The ELM411 provides all of the necessary circuitry to connect as many as three independent mechanical contacts to an electronic circuit. All mechanical contacts, whether from switches, relays, etc. will have inherent ‘bounce’ when they make or break a connection. Depending on the type of switch, this fluctuation can be quite pronounced, often being interpreted as multiple inputs by high speed digital circuits. All of the logic required to remove the bounce from most mechanical sources is provided by this circuit, without the use of additional ponents. As well, internal pull-up resistors have been provided so that the switch inputs can be...
