General 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.
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 opening, without external components.
- Internal pullup resistors for contact monitoring.
- High current drive outputs - up to 25 mA.
- Can be cascaded to provide sequential outputs Connection Diagram PDIP and SOIC (top view) VDD Out1 1 2 3 4 8 7 6 5.
