FEATURES
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.

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-
