ELM401 Datasheet (ELM) - Rotary Encoder Debounce Circuit

ELM401, Rotary Encoder Debounce Circuit

The ELM401 is an 8 pin integrated circuit that is used to ‘debounce’ the signals from a mechanical rotary (quadrature) encoder.

The low power CMOS technology used ensures that only a very small current is required over the entire 2.0 to 5.5 volt operating range.

There is no need for external filteri
