The document describes the features of the DLR/DLO/DLG1414, including dot matrix replacement, 0.145 inch high dot matrix character, 128 special ASCII characters, wide viewing angle, close vertical row spacing, fast access time, compact size for handheld equipment, built-in memory, built-in character generator, built-in multiplexing and LED drive circuitry, direct access to each digit independently and asynchronously, TTL compatible, 5 volt power, low power consumption, 20 mA per character typical, intensity coded for display uniformity, extended operating temperature range, end stackable, 4-character package.
The DLR1414 (and its DLO/DLG variants) is a four‑digit 5×7 dot‑matrix alphanumeric display module that replaces the DL1414T. It includes an integrated CMOS driver, memory, and an ASCII decoder, allowing independent asynchronous control of each digit. The module operates from a 0.5 V to 7 V supply, consumes about 20 mA per character, and offers a fast 110 ns access time.
Design notes cover maximum ratings, electrical and mechanical considerations, ESD protection, soldering guidelines, and optical recommendations such as filter selection for improved contrast. Application notes and further details are referenced in the Siemens Optoelectronic Data Book.
