NJU3713
12-BIT SERIAL TO PARALLEL CONVERTER
GENERAL DESCRIPTION
The NJU3713 is a 12-bit serial to parallel converter
especially applying to MPU outport expander.
The effective outport assignment of MPU is available
as the connection between NJU3713 and MPU using
only 4 lines.
The serial data synchronizing with 5MHz or more
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.
The hysteresis input circuit realizes wide noise
margin and the high drive-ability output buffer (25mA)
can drive LED directly.
