4-character 5 x 7 dot matrix / rohs compliant - by exemption (see page 1) serial input alphanumeric industrial display sunlight viewable: isd235x 2006-04-04 1 isd201x, isd231x, isd235x isd201x isd231x isd235x rohs compliant - by exemptiondescription 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 vert ically 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 comp atible v b input may either be tied to v cc 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 locati ons. 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: 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 fr ee 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 2006-04-04 2 isd201x, isd231x, isd235x ordering information type color of emission character height mm (inch) ordering code isd2351 isd2352 isd2353 yellow high efficiency red high efficiency green 5.08 (0.200) q68000a8142 q68000a8143 q68000a8144 isd2010 isd2011 isd2012 isd2013 red yellow high efficiency red high efficiency green 3.81 (0.150) q68000a8134 q68000a8135 q68000a8136 q68000a8137 isd2310 ISD2311 isd2312 isd2313 red yellow high efficiency red high efficiency green 5.08 (0.200) q68000a8138 q68000a8139 q68000a8140 q68000a8141 maximum ratings parameter symbol value unit operating temperature range 1) t op -55 to +100 c storage temperature range t stg -65 to +125 c supply voltage v cc to gnd v cc -0.5 to 7.0 v inputs, data out and v b -0.5 to v cc +0.5 v column input voltage v col -0.5 to 6.0 v solder temperature 1.59 mm (0.063?) below seating plane, t < 5.0 s t s 260 c allowable power dissipation, t a =25c 2) isd2010 isd2011 / isd2012 / isd2013 isd231x isd235x p tot p tot p tot p tot 0.91 0.86 1.10 1.35 w w w w

isd201x, isd231x, isd235x 2006-04-04 11 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. 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. thermal model 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, v f(led) , and forward current i f (led), of 13 ? 14.5 ma. this rise averages t j(led) =1 c. the table below shows the v f(led) for the respective displays. 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. for ease of calculations the maximum allowable electrical operat - ing condition is dependent upon the aggregate thermal resistance of the led matrixes and the two driver ics. all of the thermal man - agement 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. equation 3. for further reference see figures ?maximum allowable power dis - sipation vs. temperature?
