HT12E Encoder IC – 4-Bit RF Encoder for Wireless Remote Control and Infrared Transmission Systems

The HT12E Encoder IC – 4-Bit RF Encoder is a member of the 212 series of encoders designed for use in wireless and infrared remote control systems. It is typically paired with an HT12D decoder IC and enables reliable communication between a transmitter and receiver using RF or IR transmission mediums.

This IC encodes 12-bit parallel input data—comprising 8 address bits and 4 data bits—into a serial output, suitable for transmission through an RF module. It features a Transmission Enable (TE) pin which, when held low, initiates continuous data encoding and transmission. The HT12E is ideal for simple wireless control systems including home automation, toy control, security systems, and remote-controlled devices.
