ELM408 Datasheet (ELM) - Rotary Decoder

ELM408, Rotary Decoder

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.

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

ELM408 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
