Description
The ELM408 is an 8 pin integrated circuit that is used to convert the output from a rotary encoder into two signals (chip select, and up/down) that can be used to control various devices.
Features
- Low power CMOS design Wide supply range.
- 2.0 to 5.5 volts Complete debouncing of the encoder inputs No external filtering needed 2x and 4x decoding Can generate a write sequence Startup delay timer High current drive outputs
