ELM404 Datasheet (ELM) - Rotary Decoder

ELM404, Rotary Decoder

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.

ELM404 Features
