ELM411 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.
ELM411 Key Features
- Low power CMOS design
- typically 1mA at 5V Wide supply range
- 3.0 to 5.5 volt operation Simultaneous monitoring of three circuits Full 25msec debounce period on contact closure and o
- Internal pullup resistors for contact monitoring
- High current drive outputs
- up to 25 mA
- Can be cascaded to provide sequential outputs
ELM411 Applications
- Pushbutton interface for logic circuits
