U+2390 "⎐" Open-Circuit-Output L-Type Symbol Unicode Character

U+2390 "⎐" Open-Circuit-Output L-Type Symbol is a technical graphic used primarily in electronic circuit diagrams and logic schematics to represent an output type with an open circuit configuration, specifically one that utilizes an L-shaped or triangular logic symbol to indicate a high-impedance state where the output is not actively driven high or low. It is part of the Miscellaneous Technical block in Unicode, which contains a collection of symbols for electrotechnical and other engineering applications, and it serves as a standardized way to denote this specific output behavior in digital system documentation.
