HT12E Remote Control Encoder

The HT12E is a 212 series CMOS encoder IC designed for remote control applications; its main function is to take parallel inputs (such as address and data) and convert them into a serially coded signal, which can then be transmitted through an RF/IR module to a compatible receiver (like the HT12D). It is commonly used in remote control systems for gates, alarms, home automation, and security devices.Key Technical Features:CMOS LSI technology with low power consumption.12-bit encoding: 8 bits for address and 4 bits for data.Supports up to 4096 address combinations to avoid interference.Configurable address inputs via jumpers or DIP switches.Encoded serial output available at a single pin (DOUT).Operating voltage: 2.4V to 12 DC. (typ 5v)External oscillator controlled by a resistor..Very low standby current ( 0.1 A).PinoutDocuments:Datasheet
