ELM409 Description
The ELM409 is digital filter circuit that is used to interface mechanical contacts to electronic circuits. All mechanical contacts, whether from switches, relays, etc. will have inherent ‘bounce’ when they make or break a connection.
ELM409 Key Features
- Standard and extra long debounce times Schmitt input provides hysteresis plementary circuit outputs Needs no external ti
- typically 1 mA at 5V Wide supply range
- 3.0 to 5.5 volt operation High current drive outputs
