... PARALLEL TO SERIAL CONVERTER GENERAL DESCRIPTION The NJU3754 is an 11-bit parallel to serial converter especially applying to MCU input port expander. It can operate from 2.7V to 5.5V. The NJU3754 requires only 3-port of MCU for data transmission and realizes the effective input port assignment. The status of the input ports is output through a latch circuit, a shift register and a 3-state buffer as the serial data synchronizing with the serial clock ...

... NJU3754 TERMINAL DESCRIPTION No. SYMBOL P10 13 SO CLK FUNCTIONAL DESCRIPTION At the falling edge of CE terminal, the status P10 terminal is latched and transferred to the shift register. At the mean time, the P0 data is output from SO terminal. While CE terminal is “L”, the data from P1 to P10 in the shift register are synchronized with the falling edge of CLK terminal and output from SO terminal ...
