Monolithic Multidigit Array Displays Features: Applications: Calculator sticks Industrial controls # Data terminals # Instrumentation = Timers Hand-held instrum Event counters National's LED numeric arrays are PC board mounted, magnified, monolithic, 7 or 14 segment red digits arranged in various combinations of up to 14 digits per array. These arrays, with digit heights of 100, 110 and 140 mils (2.54, 2.794 and 3.556 mm) are intended for applications requiring small, low cost numeric indication.
