Description

The ELM411 provides all of the necessary circuitry to connect as many as three independent mechanical contacts to an electronic circuit.

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

Applications

• Pushbutton interface for logic circuits

• Limit switch monitoring

• Time delay generation
