NTE makes a good dual optoisolator in 8 pin DIP that I use for my RTTY FSK
keying and PTT. Pinout compatibility is unknown by me. Bought mine at Fry's,
where there is a NTE book with diagrams.

Subject: [WriteLog] NEC Dual Optoisolator not available from Digikey
The the 2 NEC Dual photo-transistor Output Optoisolators specified in the
specs for the W5XD Multi-function keyer are no longer available from
Digikey.
Does anyone know of an alternate source for the chips or an available pin
compatible chip from another manufacturer?
Thanx,
