NJU3754

PRELIMINARY

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

and more operation.

Furthermore, pull-up resistors on chip of P0 to P10

terminals reduce external components for key-scan

circuit, etc.
