Multidigit LED Numeric Displays Features: National Semiconductor offers a wide range of red multidigit GaAsP LED reflective displays, in 0.3", 0.5"' and 0.7" formats. The series provides the de- signer with an effective, easy to implement answer to the need for an inexpensive large numeric display. The end stackability of the 2-digit and 4-digit dis- plays allows for a wide range of options for appli- cations requiring additional digits. = Prematched light intensity of digits within each display is guaranteed to insure uniform brightness. = PCB mounting decreases overall cost per digit and allows for easier board mounting. = The optical design of this series affords an easy- to-read display with a wide viewing angle and ex- cellent ON-OFF contrast. The products listed are standard items designed to meet the majority of your needs for an inexpensive numeric display. The modular construction of these displays offers a great deal of flexibility in display format and drive considerations through modifica- tion of the PC board design. If you have a volume application not met by one of the standard product configurations listed, contact the National Sales Office nearest you for a custom LED display designed to your needs.
