7 electrical description each display device contains four 5x7 led dot matrix characters and two cmos integrated circuits, as shown in figure 4. the two cmos integrated circuits form an on-board 28 bit serial-in-parallel- out shift register that will accept standard ttl logic levels. the data input, pin 12, is connected to bit position 1 and the data output, pin 7, is connected to bit position 28. the shift register outputs control constant current sinking led row drivers. the nominal current sink per led driver is 11ma for the hcms- 200x displays, 13 ma for the hcms-230x. a logic 1 stored in the shift register enables the corresponding led row driver and a logic 0 stored in the shift register disables the correspond- ing led row driver. the electrical configuration of these cmos ic alphanumeric displays allows for an effective interface to a display controller circuit that supplies decoded character information. the row data for a given column (one 7 bit byte per character) is loaded (bit serial) into the on-board 28 bit shift register with high to low transitions of the clock input. to load decoded character informa- tion into the display, column data for character 4 is loaded first and the column data for character 1 is loaded last in the following manner. the 7 data bits for column 1, character 4, are loaded into the on-board shift register. next, the 7 data bits for column 1, character 3, are loaded into the shift register, shifting the charac- ter 4 data over one character position. this process is repeated for the other two characters until all 28 bits of column data (four 7 bit bytes of character column data) are loaded into the on-board shift register. then the column 1 input, v col pin 1, is energized to illuminate column 1 in all four characters. this process is repeated for columns 2, 3, 4 and 5. all v col inputs should be at logic low to insure the display is off when loading data. the display will be blanked when the blanking input v b , pin 8, is at logic low regardless of the outputs of the shift register or whether one of the v col inputs is energized. refer to application note 1016 for drive circuit information. esd susceptibility the hcms-200x/-230x series displays have an esd susceptibil- ity ratings of class 3 per dod- std-1686 and class b per mil- std-883c. it is recommended that normal cmos handling precautions be observed with these devices. figure 1. maximum allowable power dissipation vs ambient temperature as a function of thermal resistance junction-to-ambient, r q j-a . derated operation assumes r q pc-a = 35 c/w per display for the printed circuit board. t j (ic) max = 125 c. figure 2. relative luminous intensity vs display pin temperature figure 3. peak column current vs column voltage
