DESCRIPTION
The SLR/SLO/SLG/SLY2016 is a four digit 5 x 7 dot ma
module with a built-in CMOS integrated circuit. This dis
stackable.
The integrated circuit contains memory, a 128 ASCII RO
multiplexing circuitry and drivers. Data entry is asynchr
play system can be built using any number of SLR/SLO
since each digit can be addressed independently and w
display the character last stored until replaced by anoth
System interconnection is very straightforward. Two ad
A1) are normally connected to the like-named inputs of
the system.
Data lines are connected to all SLR/SLO/SLG/SLY2016s
parallel as is the write line (WR). The display will then b
write-only memory.
The SLR/SLO/SLG/SLY2016 has several features super
tive devices. 100% burn-in processing insures that the
SLY2016 will function in more stressful assembly and u
ments. True “blanking” allows the designer to dim the
more flexibility of display presentation. Finally the CLR
will clear the ASCII character RAM.

Loading Data
The desired data code (D0–D6) and digit address (A0, A1) must
be held stable during the write cycle for storing new data.
Data entry may be asynchronous. Digit 0 is defined as right
hand digit with A1=A2=0.`
Clearing the entire internal four-digit memory can be accom-
plished by holding the clear (CLR) low for 1.0 msec minimum.
The clear function will clear the ASCII RAM. Loading an illegal
data code will display a blank.

Display Blanking
Blank the display by loading a blank or space into each digit of
the display or by using the (BL) display blank input. Setting the
(BL) input low does not affect the contents of data memory.
A flashing circuit can easily be constructed using a 555 as table
multivibrator. Figure 3 illustrates a circuit in which varying R1
(100K~10K) will have a flash rate of 1.0 Hz~10 Hz.
The display can be dimmed by pulse width modulating the (BL)
at a frequency sufficiently fast to not interfere with the internal
clock. The dimming signal frequency should be 2.5 kHz or
higher. Dimming the display also reduces power consumption.

Design Considerations
For details on design and applications of the SLX2016 in multi-
ple display systems, refer to Appnote 15 at www.infineon.com/
opto.
Electrical & Mechanical Considerations
Voltage Transient Suppression
We recommend that the same power supply be used for the
display and the components that interface with the display to
avoid logic inputs higher than
V
CC
. Additionally, the LEDs may
cause transients in the power supply line while they change
display states. The common practice is to place .01 mF capaci-
tors close to the displays across
V
CC
and GND, one for each
display, and one 10
µ
F capacitor for every second display.
ESD Protection
The CMOS IC of the SLX2016 is resistant to ESD damage and
capable of withstanding discharges less than 2.0 kV. However,
take all the standard precautions, normal for CMOS compo-
nents. These include properly grounding personnel, tools,
tables, and transport carriers that come in contact with
unshielded parts. If these conditions are not, or cannot be met,
keep the leads of the device shorted together or the parts in
anti-static packaging.
Soldering Considerations
The SLX2016 can be hand soldered with SN63 solder using a
grounded iron set to 260
°
C.
Wave soldering is also possible following these conditions: Pre-
heat that does not exceed 93
°
C on the solder side of the PC
board or a package surface temperature of 85
°
C. Water soluble
organic acid flux (except carboxylic acid) or rosin-based RMA
flux without alcohol can be used.
Wave temperature of 245
°
C ±5
°
C with a dwell between 1.5 sec.
to 3.0 sec. Exposure to the wave should not exceed tempera-
tures above 260
°
C for five seconds at 0.063" below the seating
plane. The packages should not be immersed in the wave.
Post Solder Cleaning Procedures
The least offensive cleaning solution is hot D.I. water (60
°
C) for
less than 15 minutes. Addition of mild saponifiers is accept-
able. Do not use commercial dishwasher detergents.
For faster cleaning, solvents may be used. Carefully select any
solvent as some may chemically attack the nylon package.
Maximum exposure should not exceed two minutes at ele-
vated temperatures. Acceptable solvents are TF (trichorotrifluo-
rethane), TA, 111 Trichloroethane, and unheated acetone.
Note:
Acceptable commercial solvents are: Basic TF, Arklone,
P. Genesolv, D. Genesolv DA, Blaco-Tron TF, Blaco-Tron TA,
and Freon TA.
For further information refer to Appnotes 18 and 19 a
com/opto.
An alternative to soldering and cleaning the disp
to use sockets. Standard pin DIP sockets .300" w
centers work well for single displays. Multiple d
blies are best handled by longer SIP sockets or D
when available for uniform package alignment. S
facturers are Aries Electronics, Inc., Frenchtown
Manufacturing, New Brunswick, NJ; Robinson-N
Albany, IN; and Samtec Electronic Hardware, Ne

Optical Considerations
The .180" high characters of the SLX2016 gives
to eight feet. Proper filter selection enhances r
this distance.
Filters enhance the contrast ratio between a lit LED
ter background intensifying the discrimination of dif
ters.The only limitation is cost. Take into considerati
lighting environment for the best cost/benefit ratio f
Incandescent (with almost no green) or fluoresc
almost no red) lights do not have the flat spectra

tive way to strengthen contrast ratios.The SLR2
dard red display and should be matched with lon
pass filter in the 600 nm to 620 nm range.
The SLO2016 is a high efficiency red display and
matched with a long wavelength pass filter in the
nm range. The SLG/SLY2016 should be matched

ple colors, neutral density gray filters offer the bes

Hoya Optics, Inc., Fremont, CA.
Unacceptable solvents contain alcohol, methanol, methylene chlo-
ride, ethanol, TP35, TCM, TMC, TMS+, TE, or TES. Since many
commercial mixtures exist, contact a solvent vendor for chemical
composition information. Some major solvent manufacturers are:
Allied Chemical Corporation, Specialty Chemical Division, Morris-
