Electrical Description
Each display device contains four
5x7 LED dot matrix characters
and two CMOS integrated circuits,
as shown in Figure 4. The two
CMOS integrated circuits form an
on-board 28 bit serial-in-parallel-
out shift register that will accept
standard TTL logic levels. The
Data Input, pin 12, is connected
to bit position 1 and the Data
Output, pin 7, is connected to bit
position 28. The shift register
outputs control constant current
sinking LED row drivers. The
nominal current sink per LED
driver is 11mA for the HCMS-
200X displays, 13 mA for the
HCMS-230X. A logic 1 stored in
the shift register enables the
corresponding LED row driver
and a logic 0 stored in the shift
register disables the correspond-
ing LED row driver.
The electrical configuration of
these CMOS IC alphanumeric
displays allows for an effective
interface to a display controller
circuit that supplies decoded
character information. The row
data for a given column (one 7 bit
byte per character) is loaded (bit
serial) into the on-board 28 bit
shift register with high to low
transitions of the Clock input. To
load decoded character informa-
tion into the display, column data
for character 4 is loaded first and
the column data for character 1 is
loaded last in the following
manner. The 7 data bits for
column 1, character 4, are loaded
into the on-board shift register.
Next, the 7 data bits for column 1,
character 3, are loaded into the
shift register, shifting the charac-
ter 4 data over one character
position. This process is repeated
for the other two characters until
all 28 bits of column data (four 7
bit bytes of character column
data) are loaded into the on-board
shift register. Then the column 1
input, V
pin 1, is energized to
illuminate column 1 in all four
characters. This process is
repeated for columns 2, 3, 4 and
5. All V
inputs should be at
logic low to insure the display is
off when loading data. The
display will be blanked when the
blanking input V
, pin 8, is at
logic low regardless of the
outputs of the shift register or
whether one of the V
COL
inputs is
energized.
Refer to Application Note 1016
for drive circuit information.
ESD Susceptibility
The HCMS-200X/-230X series
displays have an ESD susceptibil-
ity ratings of CLASS 3 per DOD-
STD-1686 and CLASS B per MIL-
STD-883C. It is recommended
that normal CMOS handling
precautions be observed with
these devices.
