NJU3716A 16-BIT SERIAL TO PARALLEL CONVERTER GENERAL DESCRIPTION PACKAGE OUTLINE The NJU3716A is a 16-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 NJU3716A 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 NJU3716AM NJU3716AVC2 the data are output from parallel output buffer through serial in parallel out shift register and parallel data latches. Furthermore, the NJU3716A outputs the serial data from SO terminal through the shift register. Therefore, it connects with other SIPO ICs like as NJU3711A in cascade for expanding the parallel conversion outputs. The hysteresis input circuit realizes wide noise margin and the high drive-ability output buffer (25mA) can drive LED directly.
