Description :

The NJU3714 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 NJU3714 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.

Furthermore, the NJU3714 output the serial data from SO terminal through the shift register, therefore output bit number can increase by cascade connection. The hysteresis input circuit realizes wide noise margin and the high drive-ability output buffer (25mA) can drive LED directly.
