Description: 1. HT12D Overview: HT12D is a versatile decoder integrated circuit (IC) specifically designed for use in radio control systems and various IoT projects involving 1-wire bus communication. 2. Features: Supports up to 16 individual channels with each channel capable of handling multiple transmitters. It offers automatic learning function, making it easy to bind new receivers to the corresponding channels. 3. Operating Modes: Operates in both normal and reverse polarity modes for added flexibility when designing radio control systems. 4. Input Signal: Accepts standard RC receiver input signals of 1.5-6V DC, making it compatible with most common remote controller setups. 5. Output Signals: Provides open collector outputs that can drive inductive loads like relays or solenoids. This makes the HT12D suitable for controlling various actuators or devices in IoT projects. 6. Low Power Consumption: Consumes minimal power with a typical quiescent current of only 4mA, making it ideal for bat
