Window
The ISD201X/231X/235X are four digit 5 x 7 dot matrix serial input
alphanumeric displays. The displays are available in red, yellow,
high efficiency red, or high efficiency green. The package is a
standard twelve-pin hermetic DIP with glass lens. The display can
be stacked horizontally or vertically to form messages of any
length.
These displays have two fourteen-bit CMOS shift registers with
built-in row drivers. These shift registers drive twenty-eight rows
and enable the design of customized fonts. Cascading multiple
displays is possible because of the Data In and Data Out pins. Data
In and Out are easily input with the clock signal and displayed in
parallel on the row drivers. Data Out represents the output of the
7th bit of digit number four shift register. The shift register is level
triggered. The like columns of each character in a display cluster
are tied to a single pin (see Block Diagram). High true data in the
shift register enables the output current mirror driver stage
associated with each row of LEDs in the 5 x 7 diode array.
The TTL compatible VB input may either be tied to VCC for maximum
display intensity or pulse width modulated to achieve intensity
control and reduce power consumption.
In the normal mode of operation, input data for digit four, column
one is loaded into the seven on-board shift register locations one
through seven. Column one data for digits 3, 2 and 1 is shifted into
the display shift register locations. Then column one input is
enabled for an appropriate period of time, T. A similar process is
repeated for columns 2, 3, 4 and 5. If the decode time and load data
time into the shift register is t, then with five columns, each column
of the display is operating at a duty factor of:
RoHS Compliance
The ISD201X, ISD231X, ISD235X Intelligent DisplaysTM are hermetically sealed displays using a ceramic and glass construction.
These components are not lead (Pb) free but are RoHS Compliant
based on the RoHS Compliance Directive's Annex, paragraphs 5
and 7. These exemptions allow for lead (Pb) in glass and ceramic
electronic components. Refer to the following excerpts from the
RoHS Compliance Directive Annex:
T DF = -------------------5 (T + 1 )
Applications of lead, mercury, cadmium and hexavalent chromium,
which are exempted from the requirements of Article 4(1)
T+t, allotted to each display column, is generally chosen to provide
the maximum duty factor consistent with the minimum refresh rate
necessary to achieve a flicker free display. For most strobed
display systems, each column of the display should be refreshed
(turned on) at a minimum rate of 100 times per second.
With columns to be addressed, this refresh rate then gives a value
for the time T+t of: 1⁄ [5 x (100)]=2.0 msec. If the device is operated
at 5.0 MHz clock rate maximum, it is possible to maintain t<T. For
short display strings, the duty factor will then approach 20%.

ISD201X, ISD231X, ISD235X
The small alphanumeric displays are hybrid LED and CMOS
assemblies that are designed for reliable operation in commercial
and industrial environments. Optimum reliability and optical
performance will result when the junction temperature of the LEDs
and CMOS ICs are kept as low as possible.
A thermal resistance of 28°C/W results in a typical junction rise of
6°C.
See Equation 2 below.
For ease of calculations the maximum allowable electrical operating condition is dependent upon the aggregate thermal resistance
of the LED matrixes and the two driver ICs. All of the thermal management calculations are based upon the parallel combination of
these two networks which is 15°C/W. Maximum allowable power
dissipation is given in Equation 3.
Thermal Modeling
ISD displays consist of two driver ICs and four 5 x 7 LED matrixes.
A thermal model of the display is shown in Figure „Thermal Model“.
It illustrates that the junction temperature of the semiconductor =
junction self heating + the case temperature rise + the ambient
temperature.
Equation 1 shows this relationship.

See Equation 1 below.
The junction rise within the LED is the product of the thermal
impedance of an individual LED (37°C/W, DF=20%, F=200 Hz),
times the forward voltage, VF(LED), and forward current IF(LED), of
13 – 14.5 mA. This rise averages TJ(LED)=1°C. The Table below
shows the VF(LED) for the respective displays.

Optical Considerations
The light output of the LEDs is inversely related to the LED diode’s
junction temperature as shown in „Normalized Luminous Intensity
vs. Junction Temperature“ (page 12). For optimum light output,
keep the thermal resistance of the socket or PC board as low as
possible.
The junction rise within the LED driver IC is the combination of the
power dissipated by the IC quiescent current and the 28 row driver
current sinks. The IC junction rise is given in Equation 2.
Equation 1.
T J ( LED ) = P LED Z θJ C + P CASE ( R θJC + R θCA )+ T A
T J ( LED ) = [( I COL ⁄ 28 )V F ( LED ) Z θJC ] + [ ( n ⁄ 35 )I COL DF ( 5V COL ) + V CC I CC ] ⋅ [ R θJC + R θCA ] + T A
Equation 2.
T J ( IC ) = P COL ( R θJC + R θCA ) + T A
T J ( IC ) = [ 5 ( V COL – V F ( LED ) ) ⋅ ( I COL ⁄ 2 ) ⋅ ( n ⁄ 35 )DF + V CC ⋅ I CC ] ⋅ [ R θJC + R θCA ] + T A

When mounted in a 10°C/W socket and operated at Absolute
Maximum Electrical conditions, the display will show an LED
junction rise of 17°C. If TA=40°C, then the LED’s TJ will be 57°C.
Under these conditions the following Figure „Max. LED Junction
Temperature vs. Socket Thermal Resistance“ shows that the lV will
be 75% of its 25°C value.

Packing
Please use the recycling operators known to you. We can also help you – get in touch with your nearest sales office.
By agreement we will take packing material back, if it is sorted. You must bear the costs of transport. For packing
material that is returned to us unsorted or which we are not obliged to accept, we shall have to invoice you for any costs
incurred.
Components used in life-support devices or systems must be expressly authorized for such purpose! Critical

Remarks:
1)
Operation above +100°C ambient is possible if the following conditions are met.
The junction should not exceed TJ=125°C and the case temperature (as measured at pin 1 or the back of the display)
should not exceed TC=100°C.
2)
Maximum allowable dissipation is derived from:
VCC=5.25 V, VB=2.4 V, VCOL=3.5 V 20 LEDs on per character, 20% DF.
3)
Dimensions are specified as follows: inch (mm)
4)
VB Pulse Width Frequency—50 kHz (max.)
5)
All typical values specified at VCC=5.0 V and TA=25°C unless otherwise noted.
6)
The displays are categorized for luminous intensity with the intensity category designated by a letter code on the
bottom of the package.
7)
The luminous sterance of the LED may be calculated using the following relationships:
LV (cd/m2) = lV (Candela)/A (Meter)2
LV (Footlamberts) = p lv (Candela)/A (Foot)2
A=5.3 x 10–8 m2 = 5.8 x 10–7 (Foot)2
8)
Dominant wavelength (ldom) is derived from the CIE chromaticity diagram and represents the single wavelength
which defines the color of the device.
9)
All typical values specified at VCC=5.0 V and TA=25°C unless otherwise noted.
10)
The luminous intensity is measured at TA=TJ=25°C. No time is allowed for the device to warm up prior to
measurement.
11)
A critical component is a component used in a life-support device or system whose failure can reasonably be
expected to cause the failure of that life-support device or system, or to affect its safety or the effectiveness of that
device or system.
12)
Life support devices or systems are intended
(a) to be implanted in the human body,
or
(b) to support and/or maintain and sustain human life.
If they fail, it is reasonable to assume that the health or the life of the user may be endangered.
