Description
These standard solid state displays have a 7.4 mm (0.29 inch) dot matrix character and an on-board IC with data memory latch/decoder and LED drivers in a glass/ceramic package.
The hermetic HDSP-078x,-079x/-088x displays utilize a solder glass frit seal. The HDSP-098X displays utilize an epoxy glass-to ceramic seal.
The numeric devices decode positive BCD logic into characters “0-9,” a “–” sign, decimal point, and a test pattern. The hexadecimal devices decode positive BCD logic into 16 characters, “0-9, A-F.” An input is provided on the hexadecimal devices to blank the display (all LEDS off) without losing the contents of the memory.
The over range device displays “± 1” and right hand decimal point and is typically driven via external switching transistors.
