NJU3730 PRELIMINARY 2 I C to PARALLEL CONVERTER GENERAL DESCRIPTION PACKAGE OUTLINE The NJU3730 is a serial-to-parallel converter IC, 2 which converts I C serial data into 3 bits parallel data. The NJU3730 incorporates selectable three kinds of 2 I C-slave-address, which are used to distinguish one of NJU3730M three NJU3730s. Thus, maximum three of the NJU3730 2 can be connected onto the same I C-bus and each 2 NJU3730 operates as a controller for non-I C device or extensive ports. 2 The NJU3730 is suitable for I C-BUS applications such as TV, AV amplifier, mini Stereo component, speaker system and others.
