T, (IC) MAX = 126C, Electrical Description Each display device contains four 5x7 LED dot matrix charac- ters 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 stan- dard 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 dis- plays, 13 mA for the HCMS- 230X. A logic 1 stored in the shift register enables the corre- sponding LED row driver and a logic 0 stored in the shift regis- ter disables the corresponding LED row driver. The electrical configuration of these CMOS IC alphanumeric displays allows for an effective 2002/.2302/-2004/.2304 HCMS-~ 2000/-2300 HCMS-2001/-2301 -2303 HCMS-. t : RELATIVE LUMINOUS INTENSITY -40 -20 Q 20 40 60 80; 100 Ta- AMBIENT TEMPERATURE ~C Figure 2. Relative Luminous Intensity vs Display Pin Tempera- ture 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 charac- ter information 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 regis- ter, shifting the character 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, Voor pin 1, is energized to illuminate column 1 in all 4-184 HCMS-230X / SERIES { | i i HCMS-200X SERIES HEMS-2300 {28 LED PIXELS ILLUMINATED) PEAK COLUMN CURRENT mA Vcou> | 0 1 2 3 4 5 6 Veo. - COLUMN VOLTAGE - v Figure 3.

The display will be blanked when the blanking input V,,, pin 8, is at logic low regardless of the outputs of the shift register or whether one of the V,,., inputs is energized. Refer to Application Note 1016 for drive circuit information. ESD Susceptibility The HCMS-200X/-230X series displays have an ESD suscepti- bility ratings of CLASS 3 per DOD-STD-1686 and CLASS B per MIL-STD-883C. It is recom- mended that normal CMOS handling precautions be ob- served with these devices.COLUMN ORIVE INPUTS COLUMN 172345 BLANKING CONTROL, Ve SERIAL DATA INPUT CLOCK Figure 4.

Soldering and Post Solder Cleaning These displays may be soldered with a standard wave solder process using either an RMA flux and solvent cleaning or an OA flux and aqueous cleaning. For optimum soldering, the solder wave temperature should be 245C and the dwell time for any display lead passing through the wave should be 1 1/ 2 to 2 seconds. The recom- mended solvent for post solder cleaning is Genesolv DES, manufactured by Allied Chemi- cal. For aqueous cleaning, a water temperature of 60C ROWS 1-7 ROWS 1-7 CONSTANT CURRENT SINKING LED ORIVERS ROWS 8-14 ROWS 15-21 2BBIT SIPO SHIFT REGISTER (140F) with an immersion time not exceeding 15 minutes is rec- ommended.
