General 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, provid ing 318 = 387,420,489 combinations. Some ICs of this series provide 4 to 8 data bits for controlling.

Features

■ Single-Chip CMOS construction
