Address/Data Sequence
The following provides the address/data sequence table for various models of the 2
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 ).
