HT12D RF Decoder IC (18-Pin DIP)

Decode remote wireless control signals cleanly and establish secure data links with the industry-standard HT12D Holtek RF Decoder IC. Specifically engineered for wireless remote control applications, home automation architectures, and anti-theft security alarm systems, this 18-pin Dual In-line Package (DIP) chip acts as the essential paired companion to the HT12E Encoder IC. Utilizing a highly efficient 2^12 series decoding architecture, it continuously interfaces with 433MHz or 315MHz RF receiver modules to monitor transmitted address bits. When it intercepts a valid signal match with its hardware-configured address lines twice in succession, it decodes and latches the data onto its 4 parallel data output pins while triggering its dedicated Valid Transmission (VT) status pin high. Operating across a wide 2.4V to 12V DC input voltage range with built-in low power consumption, it integrates seamlessly into prototype breadboards, wireless relay modules, and custom micro-controller interfaces.
