5 operational considerations electrical these devices use a modified 4 x 7 dot matrix light emitting diode to display decimal/hexa- decimal numeric information. the high efficiency red and yellow leds are gaasp epitaxial layer on a gap transparent substrate. the green leds are gap epitaxial layer on a gap transparent substrate. the leds are driven by constant current drivers, bcd information is accepted by the display memory when the enable line is at logic low and the data is latched when the enable is at logic high. using the enable pulse width and data setup and hold times listed in the recommended operating conditions allows data to be clocked into an array of displays at a 6.7 mhz rate. the decimal point input is active low true and this data is latched into the display memory in the same fashion as the bcd data. the decimal point led is driven by the on-board ic. the blanking control input on the hexadecimal displays blanks (turns off) the displayed information without disturbing the contents of display memory. the display is blanked at a minimum threshold level of 2.0 volts. when blanked, the display standby power is nominally 250 mw at t a = 25 c. mechanical the primary thermal path for power dissipation is through the device leads. therefore, to insure reliable operation up to an ambient temperature of +85 c, it is important to maintain a case- to-ambient thermal resistance of less than 35 c watt/device as measured on top of display pin 3. for information on soldering and post solder cleaning see applica- tion note 1027, soldering led components . contrast enhancement these display devices are designed to provide an optimum on/off contrast when placed behind an appropriate contrast enhancement filter. for further information, please refer to application note 1015, contrast enhancement techniques for led displays. over range display the over range devices display 1?and decimal point. the character height and package configuration are the same as the numeric and hexadecimal devices. character selection is obtained via external switching transistors and current limiting resistors. note: 1. dimensions in millimetres and (inches). package dimensions pin character 1 2,3 4 8 +1xx1 -0xx1 1x1xx decimal point x x 1 x blank 0 0 0 0 notes: 0: line switching transistor in figure 7 cutoff. 1: line switching transistor in figure 7 saturated. x: 'don't care'
