The HDSP-253x is ideal for applications where displaying eight or more characters of dot matrix information in an aesthetically pleasing manner is required. These devices are eightdigit, 5 x 7 dot matrix, alphanumeric displays. The 5.0 mm (0.2 inch) high characters are packaged in a 0.300 inch (7.62 mm) 30 pin DIP. The on-board CMOS IC has the ability to decode 128 ASCII characters, which are permanently stored in ROM. In addition, 16 programmable symbols may be stored in onboard RAM. Seven brightness levels provide versatility in  Device Selection Guide AlGaAs Red HER Orange Yellow Green HDSP-2534 HDSP-2532 HDSP-2530 HDSP-2531 HDSP-2533 adjusting the display intensity and power consumption. The HDSP-253x is designed for standard microprocessor interface techniques. The display and special features are accessed through a bidirectional eight-bit data bus.
