com 12-BIT SERIAL TO PARALLEL CONVERTER GENERAL DESCRIPTION The NJU3713A is a 12-bit serial to parallel converter especially applying to MPU outport expander.
It can operate from 2.
4V to 5.
5V.
The effective outport assignment of MPU is available as the connection between NJU3713A 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.
