Bringing this will clear Character Address Register, Control Word Register, RAM, blanks display. This action leaves display Character Address Brightness Level 100%. Electrical Mechanical Considerations Interconnect Considerations Optimum product performance when following electrical mechanical recommendations adopted. SCD5510XA's constructed high speed CMOS process, consequently high speed noise SERIAL DATA, SERIAL DATA CLOCK, LOAD RESET lines cause incorrect data written into serial shift register. Adhere transmission line termination procedures when using fast line drivers long cables (>10 cm). Good digital grounds (pins power supply decoupling (pins will insure that (<400 peak) switching currents generate localized ground bounce. Therefore recommended that each display package capacitor between ground. When internal Clock being used connect CLKSEL VCC. those applications where RESET will connected system's reset control, recommended that this connected center node series network. Thus upon initial power RESET will held allowing adequate time system power supply stabilize. SCD5510XA allows power dissipation 1.29 power dissipation maximum operating temperature 85°C. Approximately this power dissipated board connection (pins 23). Optimum thermal reliability obtained connecting pins common located both sides board. This technique offers thermal resistance system ambient. Protection input protection structure SCD55100A/1A/2A/3A/4A provides significant protection against damage. capable withstanding discharges greater than Take standard precautions, normal CMOS components. These include properly grounding personnel, tools, tables, transport carriers that come contact with unshielded parts. these conditions not, cannot met, keep leads device shorted together parts anti-static packaging.
Soldering Considerations SCD55100A/1A/2A/3A/4A hand soldered with SN63 solder using grounded iron 260°C. Wave soldering also possible following these conditions: Preheat that does exceed 93°C solder side board package surface temperature 85°C. Water soluble organic acid flux (except carboxylic acid) rosin-based flux without alcohol used. Wave temperature 245°C ±5°C with dwell between sec. sec. Exposure wave should exceed temperatures above 260°C five seconds 0.063" below seating plane. packages should immersed wave. Post Solder Cleaning Procedures least offensive cleaning solution D.I. water (60°C) less than minutes. Addition mild saponifiers acceptable. commercial dishwasher detergents. faster cleaning, solvents used. Exercise care choosing solvents some chemically attack nylon package.

Optical Considerations 0.145" high character SCD5510XA gives readability eight feet. Proper filter selection enhances readability over this distance. Using filters emphasizes contrast ratio between character background. This will increase discrimination different characters. only limitation cost. Take into consideration ambient lighting environment best cost/benefit ratio filters. Incandescent (with almost green) fluorescent (with almost red) lights have flat spectral response sunlight. Plastic band-pass filters inexpensive effective strengthen contrast ratios. SCD55100A/2A red/high efficiency displays should matched with long wavelength pass filter range. SCD55103A/4A should matched with yellow-green bandpass filter that peaks displays multiple colors, neutral density grey filters offer best compromise.

Additional contrast enhancement gained shading displays. Plastic band-pass filters with built-in louvers offer next step contrast improvement. Plastic filters improved further with anti-reflective coatings reduce glare. trade-off fuzzy characters. Mounting filters close display reduces this effect. Take care overheat plastic filter allowing proper flow. Optimal filter enhancements gained using circular polarized, anti-reflective, band-pass filters. circular polarizing further enhances contrast reducing light that travels through filter reflects back display less than Several filter manufacturers supply quality filter materials.
