Functional Description
Operation
The 2
12
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 en-
coder output completes its final cycle and then stops as shown below.
