Product Summary

The 10937P-50 Alphanumeric Display Controller is a MOS/LSI general purpose display controller designed to interface to segmented displays (vacuum fluorescent or LED). The 10937P-50 will drive displays with up to 16 characters with 14 or 16 segments. Segment decoding within each device provides for the ASCII character set (upper case only). No external driver circuitry of 10937P-50 is required for displays that operate on 20mA of drive current up to 50V. A 16×64-bit segment decoder provides internal ASCII character set decoding for the display.
