When data is being transmitted continously the VT line will stay high while valid data is being received.

HT12D RF Decoder IC Pinout, Details, Equivalent & Datasheet

The 4-bit data that is received can be obtained on pins AD0 to AD1 and an address of 8-bit has to be set using hh12d pins A0 to A7. Post as a guest Name. Be the first to write a review. I have made following project using a Holtek HTD decoder: Return and Refund Policy.

In simple terms, HT12D converts the serial input into parallel outputs. Arduino based GPS receiver. The input data code is decoded when no error or unmatched codes are found.

In the above circuit I have set the 8-bit address data as 0b, by connecting all address pins to ground. Customers who bought this product also purchased Photograph just for reference.

The data on 4 bit latch type output pins remain unchanged until new is received. So if you are working on a project which has to transmit a 4-bit data from one end to other either by wire or wireless then this IC pair will be best suited for you.

Please submit the url of the better price you saw. We should set the bits in same pattern on Encoder and Decoder IC to pair them.

HT12D Decoder IC

Easy Interface with and RF or an Infrared transmission medium. TB Stepper Motor Driver 4. Submitted by admin on 27 October Virgin Galactic — Commercial Space Flight. This high-density System-in-Package SiP integrates controller, power switches, and support components. The Decoder receive the serial address and data from its corresponding decoder, transmitted by a carrier using an RF transmission medium and gives output to the output pins hf12d processing the data.


Can datashet provide a link to the receiver. They don’t show a maximum so maybe it has current limiting, but some further buffering of the data lines is probably in order. These are the 8-bit address bits, which is used to protect your data. The IC has a built in oscillator. My problem is that when I press any switch on the transmitter and cut power to the transmitter by holding push switch, the receiver end is still showing a LED output. Can be used in Home automation for short range remote switching Safety systems like Burglar alarm system, Smoke or Fire alarm system etc.
