Data Sheet
Description
This sunlight viewable 5 x 7
LED four-character display is
contained in 12 pin dual-in-line
packages designed for
displaying alphanumeric
information. The display is
designed with on-board CMOS
integrated circuits. Two CMOS
ICs form an on-board 28-bit
serial-in/parallel-out shift
register with constant current
output LED row drivers.
Decoded column data is clocked
into the on-board shift register
for each refresh cycle. Full
character display is achieved
with external column strobing.

Electrical Description
The display contains four 5 x 7
LED dot matrix characters and
two CMOS integrated circuits,
as shown in Figure 1. 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. 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
corresponding 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 information 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 character 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, VCOL pin 1, is
energized to illuminate column
1 in all four characters. This
process is repeated for columns
2, 3, 4 and 5. All VCOL inputs
should be at logic low to insure
the display is off when loading
data. The display will be
blanked when the blanking
input VB, pin 8, is at logic low
regardless of the outputs of the
shift register or whether one of
the VCOL inputs is energized.

for drive circuit information.

Contrast Enhancement
The display has an ESD
susceptibility ratings of CLASS
3 of MIL-STD-883E, HBM. It is
recommended that normal
CMOS handling precautions be
observed with these devices.
When used with the proper
contrast enhancement filters,
the display is readable in
sunlight.
Soldering and Post Solder Cleaning
These displays may be soldered
with a standard wave solder
process using either an RMA
flux and solvent cleaning or an
OA flux and aqueous cleaning.
For optimum soldering, the
solder wave temperature should
be 245 °C and the dwell time
for any display lead passing
through the wave should be 1.5
to 2 seconds. For more detailed
information, refer to Application
Note 1027, Soldering LED
Components.
