Description: 2 12 Series of Decoders. Manufacturer: Holtek Semiconductor Inc.

HT12D/HT12F Rev. 1.40 4 August 30, 2022 Functional Description Operation The 212 series of decoders provides various combina-tions of addresses and data pins in different packages so as to pair with the 212 series of encoders. The decoders receive data that are transmitted by an encoder and interpret the first N bits of code period as

HT12D IC is a CMOS series 12-bit RF decoder. Mostly remote control applications have this technology. It gets to interface with the third device and helps it to decode 12-bits data. In this decoder, only 4-bits are data the remaining part is the address.

2013年6月16日 · HT12D is a 2 12 series decoder IC (Integrated Circuit) for remote control applications manufactured by Holtek. It is commonly used for radio frequency (RF) wireless applications. By using the paired HT12E encoder and HT12D decoder we can transmit 12 bits of parallel data serially.

Os CI ‘s HT12E e HT12D simplificam a comunicação sem fio ou com fio entre dispositivos, como no caso de sistemas que utilizam módulos RF. O HT12E atua como codificador, transformando os dados paralelos em dados seriais que são enviados pelo transmissor RF.

HT12D是一款采用18引脚DIP封装的2^12解码器。该解码器是一系列用于遥控系统应用的CMOS LSI。它与Holtek的2^12编码器配对使用。为了正确操作，应选择一对具有相同地址数和数据格式的编码器/解码器。

Of the 2 series of decoders, the HT12F has no data output pin but its VT pin can be used as a momentary data output. The HT12D, on the other hand, provides 4 latch type data pins whose data remain unchanged until new data. The oscillator is disabled in the standby state and activated when a logic high signal applies to the DIN pin.

The HT12D is an integrated circuit designed for use in remote control systems. It is a series decoder IC for remote control applications manufactured by Holtek. It is commonly paired with the HT12E encoder IC in remote control systems.

How to use a HT12D RF Decoder. The primary function of HT12D is to decode the 12-bit that is received by the input pin. Since the IC comes with an in-built Oscillator it is very easy to make this IC work. The IC is should be powered by 5V (pin 18) and the ground pin (pin 9) is grounded.
