I am making a circuit that uses the H11AA1 (http://www.vishay.com/docs/83608/h11aa1.pdf). This is a bidirectional opto-isolator. enter image description here

I want to simulate it in Proteus, but in the libraries there are only uni-directional opto-isolators. ¿How can I simulate this device, or something similar?

I am suppose to have something like this: enter image description here

Thanks in advance

    \$\begingroup\$ Simply use two single LED opto-isolators with the output CE's in parallel and the input LED connection reversed. \$\endgroup\$

how about rectifying that signal and then use a unirectional opto-isolator enter image description here
