The ELM404 is an 8 pin integrated circuit that is used to convert the output from a rotary encoder into three signals (chip select, clock and up/down) that can be used to control various devices.
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 filtering or debounce circuits with the ELM404, as this is all performed within the integrated circuit.
