NJU3754 11-BIT 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. The hysteresis input circuit of the serial clock terminal realizes 5MHz operation. Furthermore, pull-up resistors on chip of P0 to P10 terminals reduce external components for key-scan circuit, etc.
