... Input Buffering If a cable length of 6 inches or more is used, all inputs to the display should be buffered with a tri-state non-inverting buffer mounted as close to the display as conveniently possible. Recommended buffers are: 74LS245 for the data lines and 74LS244 for the control lines. ...

... Digit 3 (leftmost) Bit D7 of any of the display digit locations is used to allow an at- tribute to be assigned to that digit. The attributes are discussed in the next section. If Bit D7 is set to a one, that character will be dis- played using the attribute. If bit D7 is cleared, the character will dis- play normally ...

Blink (D5): The entire display can be caused to blink at a rate of approximately 2 setting bit D5 in the Control Word. This blink- ing is independent of the state all character locations. ...

... Electrical and Mechanical Considerations The CMOS IC of the display is designed to provide resistance to both Electrostatic Discharge Damage and Latch Up due to voltage or current surges. Several precautions are strongly recommended to avoid overstressing these built-in safeguards. ESD Protection Display users should be careful to handle the devices consistent with Standard ESD protection procedures ...

... Optical Considerations The character heights of these displays allows readability up to eight feet. Proper filter selection allows the user to build a display that can be used over this distance. Filters allow the user to enhance the contrast ratio between a lit LED and the character background. This will maximize discrimina- tion of different characters as perceived by the display user ...
