... Other remote control systems bits via infrared transmission medium upon receipt of a trigger signal. The capability to select a TE trigger on the HT12E or a DATA trigger on the HT12A further enhances the application flexibility of the 2 ries of encoders. The HT12A additionally provides a 38kHz carrier for infrared systems. ...

... The 2 series of encoders begin a 4-word transmission cycle upon receipt of a transmission enable (TE for the HT12E or D8~D11 for the HT12A, active low). This cycle will repeat itself as long as the transmission enable (TE or D8~D11) is held low. Once the transmission enable returns high the encoder output completes its final cycle and then stops as shown below ...

... A0 to AD11 for the HT12E encoder and A0 to D11 for the HT12A encoder. During information transmission these bits are transmitted with a preceding synchronization bit. If the trigger signal is not applied, the chip enters the standby mode and consumes a reduced current of less than 1 A for a supply voltage of 5V ...

... A2 A3 Transmission Enable For the HT12E encoders, transmission is enabled by applying a low signal to the TE pin. For the HT12A encoders, transmission is enabled by applying a low signal to one of the data pins D8~D11. Two Erroneous HT12E Application Circuits The HT12E must follow closely the application circuits provided by Holtek (see the Application circuits ). ...
