Operation
The UTC
UT912D
offers different packages by various combinations of addresses and data pins to pair with the
UTC
UT912E
. The decoders receive data that are transmitted by an encoder and interpret the first N bits of code
period as addresses and the last 12-N bits as data, where N is the address code number. A signal on the DIN pin
activates the oscillator, which in turn decodes the incoming address and data. The decoders will then check the
received address three times continuously. If the received address codes all match the contents of the decoder-s
local address, the 12-N bits of data are decoded to activate the output pins and the V
T
pin is set high to indicate a
valid transmission. This will last unless the address code is incorrect or no signal is received. The output of the V
T
pin is high only when the transmission is valid. Otherwise it is always low.
