Generally, 6 pin DIPs are optoisolators.

There must be exceptions, but every time I see one I start
with the assumption that it's an optoisolator.

I think the second choice would be a pair of transistors.

Found the following on the NTEINC web site.

Replace part.... With NTE part.... Product Line Data Sheets

NPN Transistor Output
6 lead DIP

1 -- Anode of LED
2 -- Cathode of LED
3 -- NC
4 -- Base of output transistor
5-- Collector of output transistor
6 -- Emitter of output transistor
