The output will be a HZ ripple on 60 HZ power lines. As long as there is AC input Vout is at close to zero volts.
Also H11AA seems to be obsolete. Anyway what is the minimum current for H11AA? Due to all these factors, someone suggested me to fatasheet another opto which works at very low current.
I am just trying to get the state of an electrical device, i.

Or do you just want to know that AC opgocoupler at least a certain rms voltage is there? This opto-coupler will work fine at 1 mA AC.

This would create lot of heat compared to the one with K and as mentioned in my query we cannot accommodate more heat. H11AA is supplied by Digikey and Mouser.
I changed R1 to K which greatly reduces heat. Email Required, but never shown. Digikey is showing H11AA as obsolete. Just saying “MCU” doesn’t tell me what it is for.
It shows operation at uA and 1mA. Sign up using Email and Password.
Take a look at an IL if you want to know what the line voltage is as the current in the two output diodes is well matched. Fairchild still makes it. Schematics you’ve tried would be nice. Sign up using Facebook.

Now Dtasheet could reduce the resistance, however the heat dissipated would be more which I don’t want. Hence I started searching for it and found one i. I calculated the voltage and found that for V AC and a series resistance of K, the current is just 0.
Ok H11AA seems to work on 1mA. Also, I’d like to know exactly what you mean by 8114 line voltage. Sorry for the long story, I am still learning.

While testing my circuit at various input voltages I found that the opto will start giving fluctuating output when my voltage is V. I am also not able to use a x-capacitor or use a transformer due to size constraints. WhatRoughBeast yes I understand that the heat dissipated is less, however my circuit sits inside a closed container and I have many of these multiple opto and resistors.
