Bi-CMOS 24-BIT SERIAL-INPUT LATCHED DRIVER
M54992P/FP
MITSUBISHI <CONTROL / DRIVER IC>
DESCRIPTION
The M54992 is a semiconductor integrated circuit consisting of 24
stages of CMOS shift registers and latches with serial inputs and
serial or parallel outputs. It is based on Bi-CMOS process
technology, and has 24 bipolar drivers at the parallel outputs.

APPLICATION
Dot drivers of thermal printer heads, serial/parallel conversion.

FUNCTION
The M54992 consists of 24 stages of D-type flip flops connected to
24 latches.
Data is input to serial input S-IN, and clock pulses are input to
clock input T. When the clock changes from low to high, the input
data enters the first shift register and data already in the shift
registers is shifted sequentially.
The serial output S-OUT is used to connect multiple M54992 to
expand the number of parallel outputs. S-OUT is connected to S-IN
of the next stage.
For parallel output. When the clock pulse changes from low to
high, latch input (LATCH) is high and output enable input (EN) is
low the serial input data at S-IN appears at output O
1
and the other
data already present is shifted sequentially to outputs O
2
through
O
24
.
The parallel outputs are inverted.
When the latch input is held low, the latch retains the stored data.
When the EN input is high, outputs O
1
through O
24
all turn off. As
the internal logic is unstable when the power is turned on, the EN
input should be kept high (setting outputs O
1
through O
24
off) until
input data is set and the internal logic is initialized.
L-GND is the GND of CMOS logic circuit and P-GND is the GND of
output driver circuits O
1
through O
24
which employ bipolar
transistors capable of large drive currents.
An output load prevention circuit is built in this IC to prevent
misoperation at power ON/OFF. Therefore, when V
CC
falls short of
the fixed level, all outputs (O
1
– O
24
) are compulsorily set to the
OFF state.
