Product Description (Detailed):

Streamline your wireless communication projects with the highly versatile HT12E Encoder IC, readily available in a convenient DIP-18 package. This essential component is specifically designed to convert parallel data inputs into serial data streams, making it a cornerstone for reliable RF communication IC applications. The HT12E operates efficiently within a wide voltage range, typically from 2.4V to 12V DC, and boasts low power consumption and high noise immunity due to its CMOS technology, ensuring stable performance in diverse environments. As a 12-bit encoder, it features 8 address pins and 4 data pins, allowing for up to 256 unique address combinations to prevent interference between multiple remote systems, enhancing security. An integrated internal oscillator simplifies implementation, requiring only a minimal external resistor for frequency setting. This fixed code encoder IC is commonly paired with its counterpart, the HT12D decoder IC, forming a robust and straightforward encoder-decoder pair ideal for various remote control systems. Whether you're building a wireless doorbell, a car alarm system, garage door opener, or integrating it into home automation and security systems, the HT12E provides a reliable and cost-effective solution for transmitting digital signals wirelessly through ASK RF modules or infrared mediums. Its parallel to serial conversion capability is fundamental for compact and efficient data transmission in numerous electronic designs.

The HT12E Encoder IC is a CMOS LSI encoder developed by Holtek as part of the 212 series remote control family. It is primarily designed for wireless data transmission via RF or IR, converting 4-bit parallel data along with 8-bit address into a serial format for communication.

This IC is commonly used with 433MHz RF transmitter modules and paired with an HT12D Decoder IC on the receiving end. Once the transmission enable (TE) pin is activated, it sends the encoded data serially for remote operation of devices.

The HT12E is an essential component for DIY RF remote control, home automation, wireless relays, and security systems.
