This document describes the features and characteristics of the HDSP series displays, including different colors, numeric and hexadecimal characters, high-efficiency red, yellow, and high-performance green. The displays have high temperature stability and performance guarantee, suitable for various applications.
The handbook describes Agilent's glass/ceramic numeric and hexadecimal displays that use a 4×7 dot‑matrix LED array. It lists three character options (numeric, hexadecimal, over‑range), three color families (high‑efficiency red, yellow, high‑performance green) and various part numbers for each color and function.
Detailed sections cover package dimensions, absolute maximum ratings, recommended operating conditions, optical and electrical characteristics, mechanical mounting, and color bin limits. The document also provides typical luminous intensity, wavelength, supply voltage, power dissipation and thermal resistance data for each display series.
