HT12E Encoder 18 DIP IC

HT12E Encoder IC is a 212 Series Encoder. It’s used in RF applications and remote control applications. Encoder and Decoder paired. This combination is useful for data transmission and able to receive 12 bits of parallel data serially. HT12E Encoder used to convert 12 bit parallel data into a serial output. The data transmitted through an RF transmitter. This 12-bit data is split into address pins (8) and data pins(4). These 8 address pins provide security code for data transmission and different receivers addressed with the same transmitter.

HT12E Encoder IC main function is to convert parallel data into serial data. It encodes the given input data and sends the output from the output pin. This output data sent to the decoder and after that data transferred. This has an inbuilt Crystal oscillator helpful for data transmission. This IC works “5 V” but operates in wide range voltage from 2.4 V -12 V. The supply pin connected with “5 V” and ground pin to ground. The data transmission will begin if the Transmission Enable pin connected to ground. For decoding a data, we require an oscillator. The oscillator connected with a resistor “1 M” ohm in 15th & 16th pin. The data has to be sent through AD0 to AD1. The address of these pins has to be set from A0 – A7. The decoder should have the same address as of the encoder so that data transmission will occur.

The HT12E Encoder IC starts working by giving enable signal to the Transmission Enable pin. The 4-word data encoded until the TE pin enabled. The output produced when the enable pin goes to HIGH. This encoder is in a standby state until the output encoding.
