Description

The UM3758 series are Single-Chip programmable encoder decoder ICs fabricated in CMOS structure for low
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, providing 3 = 387,420,489 combinations. Some ICs of this series provide 4 to 8 data bits for controlling. According to the following information, The internal address biis, 18 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 generatea low pulse. If there were any data bits, the receiver will latch these data bis at the corresponding pins for controlling.
