Product Overview
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 µA).\
