General Description
The UM3758 series are Single-Chip programmable encoder
/decoder ICs fabricated i n C M O S s t r u c t u r e f o r l o w
power consun$ion: They are enhanced for new Stage
encoder/decoder ICs to provide many more combinations
for higher security.
Most fzmbinations are achieved by UM3758-18OA, provid-
ing 3 = 387,420,489 combinations. Some ICs of this
series provide 4 to 8 data bits for controlling.
According to the following information, The inter-
n a l a d d r e s s b i i s , 1 8 bis/24pin and 12 biis/lEpin
package, tan be assigned by customer in advance
for much higher securii and confidentialii. Whenever
t h e a d d r e s s Codes of transmitter t r a n s m i t s , t h e
receiver will check the address codes with his own and
the successive two matched address codes will generate
a low pulse. If there were any data bits, the receiver
will latch these data bis at the corresponding pins
for controlling.
