HT12E (2^12 Series of Encoders)

Description

HT12E Pin?Configuration? Pin Number Pin Name Description 1 to 8 A0,A1,A2,A3,A4,A5,A6 & A7 These are the 8-bit address bits, which is used to protect your data. We should set the bits in same pattern on Encoder and Decoder IC to pair them. 9 Ground/Vss Connected to the Ground of circuit 10 to 13 AD0, AD1, AD2 & AD3 These four pins are used to send data, the data encoded here will be decoded on HT12D IC sharing the same address bits 14 Transmission Enable(TE) This pin has to be connected to Ground (0V) to enable the Transmission. 15 and 16 Oscillator pins 1 & 2 The IC has a built in oscillator. This oscillator can be used by connecting these two pins through a 1M Resistor 17 Output The Encoded 12 bit output data can be obtained from this pin 16 Vcc/Vdd This pin powers the IC, typically 5V is used. Can range from 2.4V to 12V Features 12-bit Encoder IC to be used with?HT12D Encoded data has 4 Data bits and 8 Address bits (8 4=12-bits) Commonly used for?RF and IR wireless transmission Wide supply voltage range from 2.4V to 12V, typically 5V is used Low stand by current of 0.1uA at Vcc=5V Available in 16-pin DIP, 20-pin SOP Note:?Complete Technical Details can be found at the?HT12E datasheet?given at the end of this page. HT12E Equivalent?Encoder PT2262, 74C922 Where to use HT12E Encoder IC The?IC HT12E?can be used only with its pair?HT12D. These two ICs together form an?Encoder and Decoder pair. They are 12-bit Encoders/Decoders, meaning they can transmit 12-bit a data among them.
