The HDSP-253x is a series of 8-character 5 mm smart alphanumeric displays, ideal for applications where displaying eight or more characters of dot matrix information in an aesthetically pleasing manner is required. These displays feature eight-digit, 5 x 7 dot matrix alphanumeric display. 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 on-board RAM. Seven brightness levels provide versatility in 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.
The HDSP-253x series provides eight‑digit, 5 mm high, 5×7 dot‑matrix alphanumeric displays packaged in a 30‑pin DIP. The on‑board CMOS IC decodes 128 ASCII characters stored in ROM and allows 16 user‑definable symbols in RAM. Seven brightness levels and TTL‑compatible inputs give flexibility for a wide range of applications.
Typical applications include avionics, computer peripherals, industrial instrumentation, medical equipment, portable data entry devices, telecommunications, and test equipment. The device operates over a supply voltage of 4.5 V to 5.5 V and supports standard microprocessor interfaces via an eight‑bit bidirectional data bus.
