I2C to PARALLEL CONVERTER
NJU3730
PRELIMINARY
! GENERAL DESCRIPTION
The NJU3730 is a serial-to-parallel converter IC,
which converts I2C serial data into 3 bits parallel data.
The NJU3730 incorporates selectable three kinds of
I2C-slave-address, which are used to distinguish one of
three NJU3730s. Thus, maximum three of the NJU3730
can be connected onto the same I2C-bus and each
NJU3730 operates as a controller for non-I2C device or
extensive ports.
The NJU3730 is suitable for I2C-BUS applications
such as TV, AV amplifier, mini Stereo component,
speaker system and others.
