HT12E 2 to the power 12 Series Encoder DIP-18 (HT12E DIP IC)
The HT12E is a CMOS integrated circuit specifically designed for remote control system applications. It is capable of encoding information which consists of N address bits and 12-N data bits. Each address/data input can be set to one of two logic states. Upon receipt of a transmit enable (TE active low), the HT12E begins a 4-word transmission cycle. This process is repeated as long as TE is held low. The encoded data is output as a serial stream, making it ideal for use with RF or infrared transmission media.
This IC is primarily used in burglar alarm systems, gate and garage door controllers, and car door controllers. It is a legendary component for Arduino electronics projects in India for building simple, cost-effective wireless remote controls, 4-channel RF transmitters, and wireless robotic control systems without the need for complex programming.
