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 intern 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.
