GENERAL DESCRIPTION
especially applying to MPU outport expander.
as the connection between NJU3715 and MPU using
only 4 lines.
clock can be input to the serial data input terminal and
the data are output from parallel output buffer through
serial in parallel out shift register and parallel data
latches.
margin and the high drive-ability output buffer (25mA)
can drive LED directly.
