What is HT12E and HT12D?
HT12E is used to encode the data for RF Transmitter and HT12D is used to decode the data received by RF receiver. They are capable of Encoding 12 bit of information which consists of 8 address bits and 4 data bits.
What is HT12E encoder?
HT12E is an encoder integrated circuit of 212 series of encoders. They are paired with 212 series of decoders for use in remote control system applications. It is mainly used in interfacing RF and infrared circuits. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter.
What is HT12D?
HT12D is a decoder integrated circuit that belongs to 212 series of decoders. This series of decoders are mainly used for remote control system applications, like burglar alarm, car door controller, security system etc. It is mainly provided to interface RF and infrared circuits.
How does HT12E encoder work?
It is commonly used for radio frequency (RF) applications. By using the paired HT12E encoder and HT12D decoder we can easily transmit and receive 12 bits of parallel data serially. HT12E simply converts 12 bit parallel data in to serial output which can be transmitted through a RF transmitter.
How do you test HT12E and HT12D?
The testing of IC HT12D will be measured by giving the input data to the pin AD12 and AD13 on the IC HT12E. Then, the addressing bits in the HT12D will be reviewed by using an oscilloscope.
Which IC is used in encoder?
A popular example of an Encoder is the Holtek Encoder H12E used for parallel to serial conversion. It is a type of CMOS IC with 8 address pins and 12 data pins. It is an 18 pin IC. It is used in RF communication where it converts the 12 bit parallel data to serial form.
What is RF transmitter and receiver?
The RF transmitter receives serial data and transmits it wirelessly through through its RF antenna. RF receiver receives the transmitted data and it is operating at the same frequency as that of the transmitter.
What is the output HT12D?
The HT12D is a 2^12 decoder in 18 pin DIP package. This decoder is a series of CMOS LSIs for remote control system applications. It is paired with Holtek’s 2^12 encoder. For proper operation, a pair of encoder/decoder with same number of addresses and data format should be chosen.
What is the use of encoder IC?
Encoders are digital ICs used for encoding. By encoding, we mean generating a digital binary code for every input. An Encoder IC generally consists of an Enable pin which is usually set high to indicate the working.
How does RF transmitter and receiver work?
The RF transmitter receives serial data and transmits it wirelessly through through its RF antenna. The transmission occurs at the rate of 1 Kbps – 10 Kbps. RF receiver receives the transmitted data and it is operating at the same frequency as that of the transmitter.
Which IC is used for decoder IC 74ls?
74LS138 IC
The decoder 74LS138 IC uses advanced technology like silicon (Si) gate TTL technology. These are suitable for different applications like memory address decoding otherwise data routing.
