I have been handed down a room full of electronics - my brother-in-law's father passed away - and I am the nearest relative who has a career in electronics, so... I am spending my evenings going through and identifing parts, most of which I am familiar with and have datasheets on. However, I can't find anything on these i C8702A. A web search brought me to your posting. I am hoping you have a datasheet or know where I should go to find one. Thanks, Alex
