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.
