DESCRIPTION
• Four Dot Matrix Characters
• Character Height
ISD201X—0.150"
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 pack-
age is a standard twelve-pin hermetic DIP with glass lens. The
display can be stacked horizontally or vertically to form mes-
sages of any length.
ISD231X/235X—0.200"
• ISD201X/231X, Four Colors: Red, Yellow,
High Efficiency Red, High Efficiency Green
• ISD235X, Three Colors: Yellow, High
Efficiency Red, High Efficiency Green
• Wide Viewing Angle
• Built-in CMOS Shift Registers with Constant Current
LED Row Drivers
• Shift Registers Allow Custom Fonts
• Easily Cascaded for Multiple Displays
• TTL Compatible
• End Stackable
• Operating Temperature Range:
–55°C to +100°C
• Categorized for Luminous Intensity
• Ceramic Package, Hermetically Sealed Flat Glass
Window
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. Cascad-
ing 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 V input may either be tied to V for max-

DESCRIPTION (continued)
Dimensions in Inches (mm)
ISD201X
In the normal mode of operation, input data for digit four, col-
umn 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 dis-
play is operating at a duty factor of:

T+t, allotted to each display column, is generally chosen to
provide the maximum duty factor consistent with the mini-
mum 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 possi-
ble to maintain t<T. For short display strings, the duty factor
will then approach 20%.

The small alphanumeric displays are hybrid LED and CMOS
assemblies that are designed for reliable operation in commer-
cial 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.
For ease of calculations the maximum allowable electrical oper-
ating condition is dependent upon the aggregate thermal resis-
tance 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. Maxi-
mum allowable power dissipation is given in Equation 3.
Thermal Modeling
Equation 3.
ISD displays consist of two driver ICs and four 5 x 7 LED
matrixes. A thermal model of the display is shown in Figure 9.
It illustrates that the junction temperature of the semiconductor
= junction self heating + the case temperature rise + the ambi-
ent temperature. Equation 1 shows this relationship.

The light output of the LEDs is inversely related to the LED
diode’s junction temperature as shown in Figure 10. For opti-
mum 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.
A thermal resistance of 28°C/W results in a typical junction
rise of 6°C.
See Equation 2 below.
Equation 1.
TJ(LED) = PLED
Z θJ C + PCASE (RθJC + RθCA)+ TA
TJ(LED) = [(ICOL ⁄ 28)VF (LED) ZθJC ] + [(n ⁄ 35)ICOL DF (5VCOL) + VCC ICC] [RθJC + RθCA] + TA
Equation 2.
TJ(IC) = PCOL(RθJC + RθCA) + TA
TJ(IC) = [5(VCOL – VF(LED)) (ICOL ⁄ 2) (n ⁄ 35)DF + VCC
ICC] [RθJC + RθCA] + TA
