I am looking for a replacement of a photo relay that accepts an AC line voltage and produces a TTL level output. This device is used to convert an AC signal (comming from a motor for a short period of time at certain instances) to a TTL level pulse ( used as a RESET input for a digital control circuit). I looked for opto-couplers form TI and Signetics, but the maximum reverse voltage of the input of these optocouplers is only 6V. Any ideas where I can find such a device. Thanks for the reply.
