MITSUBISHI <CONTROL / DRIVER IC>
M56694FP/GP
Bi-CMOS & DMOS 32BIT SERIAL-INPUT LATCHED DRIVER
DESCRIPTION
The M56694 is a semiconductor integrated circuit that has a builtin, 32-bit shift register and a latch of CMOS structure with serial
input and serial/parallel output, and a 32-bit totem-pole-type
parallel output driver of high pressure proof DMOS structure.
Employed are Bi-CMOS and high pressure proof DMOS
processing technology.
FEATURES
● Serial input-serial/parallel output
● Cascade connections possible through serial output
● Latch circuit included for each stage
● Driver section supply voltage: VH=120V
● Operating temperature: -20 – 75°C
APPLICATION
Vacuum Fluorescent Display ANODE DRIVER
FUNCTION
The M56694 comprises a 32-bit D type flip-flop with 32 latches
connected to its output.
In accordance with truth table 1, inputting data to SIN and clock
pulse to CLK allows SIN signal to be put into the internal shift
register when the clock changes from “H” to “L”, and
simultaneously shift register data to be shifted sequentially.
Serial output SOUT is used by connecting to the next stage
M56694 SIN when more than one M56694 is used to expand bits
in the series.
In accordance with truth table 2, parallel output allows the latch to
pass data through if LAT input is turned to “H”, and data to be
retained if LAT input is turned to “L”. Driver output HVOn allows
data from the latch to be output if BLK input is turned to “L”, and “L”
to be output if BLK input is turned to “H”, irrespective of data from
the latch.
