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.
FEATURES
APPLICATION
Dot drivers of thermal printer heads, serial/parallel conversion.
Drivers for relays and solenoids.
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
data already present is shifted sequentially to outputs O
O
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
the internal logic is unstable when the power is turned on, the EN
input should be kept high (setting outputs O
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
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
