VTL5C6 optocoupler

Optocoupler best known for use in the Pigtronix Philosopher’s Tone. Very fast response time (3.5ms). This is the Xvive reissue of the part formerly manufactured by Perkins-Elmer, Excelitas and Vactec under the same name, and the exact part used in the current Philosopher’s Tone Micro.

Note: These are unmarked (no dot). The VTL5C3 has a yellow dot, which is the only way the two types can be visually distinguished.
