SK2086 is an RCA replacement part number for a 
Dual Photo-Darlington OptoIsolator.
              _ _
   anode1   1| U |8   emitter1
 cathode1   2|   |7   collector1
 cathode2   3|   |6   collector2
   anode2   4|___|5   emitter2

The photo-darlingtons are NPN.

Limit Conditions
================
Pt	400mW	Device Dissipation
Viso	7500V	Peak Isolation Voltage

Input LED
=========
If	60mA	Max DC Foward Current
Vr	3V	Max Reverse Voltage

PhotoTransistor Characteristics
===============================
VCBO	30V	Collector to Base Voltage
VCEO	30V	Collector to Emitter Voltage
IC	30mA	Continuous Collector Current
hFE	50	Typical DC Current Gain
BW 	200KHz	Typical Bandwidth

These optoisolators are intended for use in isolating audio and video
inputs from a VCR to a HOT chassis TV set.
