Overview
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.
