Need Datasheet NEC PS2510-4 Optocoupler

[CJL5585]

I need a datasheet or pinout of a NEC PS2510-4 16 pin DIP quad optocoupler. I have made many searches without any luck.

Any help would be appreciated as this part is used to optoisolate a limit switch on a CNC motherboard.

Thanks in advance for any help.

Is this for testing or possible replacement? If you can reverse engineer some of the pins by tracing, it may be nothing more than a simple 4n25/35 equiv. etc, if it can be deduced it is a LED diode one side and photo transistor the other, it may be simple to sub. as generally many conform to this pin out.
The LED anode or cathode at least should be possible to identify by the Limit switch input and then detect the other side of the diode. And go from there.
