(see page 1) 4-Character 5 x 7 Dot Matrix / RoHS Compliant - By Exemption Serial Input Alphanumeric Industrial Display Sunlight Viewable: ISD235X ISD201X, ISD231X, ISD235X ISD231X ISD235X ISD201X RoHS Compliant - By ExemptionDESCRIPTION FEATURES The ISD201X/231X/235X are four digit 5 x 7 dot matrix serial input Four Dot Matrix Characters alphanumeric displays. The displays are available in red, yellow, Character Height high efficiency red, or high efficiency green. The package is a ISD201X 3.81 mm (0.150 ) standard twelve-pin hermetic DIP with glass lens. The display can ISD231X 5.08 mm (0.200 ) be stacked horizontally or vertically to form messages of any ISD235X 5.08 mm (0.200 ) length. Built-in CMOS Shift Registers with Constant Current These displays have two fourteen-bit CMOS shift registers with built-in row drivers. These shift registers drive twenty-eight rows LED Row Drivers and enable the design of customized fonts. Cascading multiple Wide Viewing Angle displays is possible because of the Data In and Data Out pins. Data Shift Registers Allow Custom Fonts In and Out are easily input with the clock signal and displayed in Easily Cascaded for Multiple Displays parallel on the row drivers. Data Out represents the output of the TTL Compatible 7th bit of digit number four shift register. The shift register is level End Stackable triggered. The like columns of each character in a display cluster Operating Temperature Range: are tied to a single pin (see Block Diagram). High true data in the shift register enables the output current mirror driver stage 55C to +100C associated with each row of LEDs in the 5 x 7 diode array. Categorized for Luminous Intensity The TTL compatible V input may either be tied to V for maximum B CC Ceramic Package, Hermetically Sealed Flat Glass display intensity or pulse width modulated to achieve intensity Window 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 RoHS Compliance through seven. Column one data for digits 3, 2 and 1 is shifted into TM the display shift register locations. Then column one input is The ISD201X, ISD231X, ISD235X Intelligent Displays are her- enabled for an appropriate period of time, T. A similar process is metically sealed displays using a ceramic and glass construction. repeated for columns 2, 3, 4 and 5. If the decode time and load data These components are not lead (Pb) free but are RoHS Compliant time into the shift register is t, then with five columns, each column based on the RoHS Compliance Directive s Annex, paragraphs 5 of the display is operating at a duty factor of: and 7. These exemptions allow for lead (Pb) in glass and ceramic T electronic components. Refer to the following excerpts from the DF = --------------------- RoHS Compliance Directive Annex: 5T()+1 Applications of lead, mercury, cadmium and hexavalent chromium, T+t, allotted to each display column, is generally chosen to provide which are exempted from the requirements of Article 4(1) the maximum duty factor consistent with the minimum refresh rate necessary to achieve a flicker free display. For most strobed 5. Lead in glass of cathode ray tubes, electronic components and display systems, each column of the display should be refreshed fluorescent tubes. (turned on) at a minimum rate of 100 times per second. 7. Lead in electronic ceramic parts (e.g. piezoelectronic devices) 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%.
