Electrical Characteristics
Functional Description
Normal Operation
The HT6P20X encodes and transmits address/data to a decoder upon receipt of a trigger signal. The address codes of
the HT6P20A are always transmitted as long as power (VDD) is supplied. The transmission function of the HT6P20B/D
is enabled by the D0~D7 pins (active low). The following is the transmission timing of the HT6P20X:
A complete code word of the HT6P20D consists of 3 periods as shown below.
