Hi group,

While studying the schematics of a seventies synthesizer I came across
a HTVP873D photocoupler. Does anyone know who made it and/or where I
can get a datasheet for it? Or maybe an equivalent, contemporary if
possible?

In the schematic it is drawn as a LED shining on a resistor with a
centertap. It also mentions a rank of the photocoupler as a number from
300 to 1100.

Thanks a lot,
Jenalee


P873* (* not D, not HTV....) by Hamamatsu having 5 axial leads were range of
LED to LDR
optocouplers, all 5KV isolation, Ron 200 to 10K and Roff 1 to 10M,
no mention of CT.
Response time 5 to 30mS so at least easy enough to make up one if necessary
