In may searches for a DP8303, I have found nothing. I did find with the help of those in this group that the 8304 was the same except non-inverted. Looking for this part, I found that several places list a 8286 as being the same. This is also refered to as a uPD71086. While looking at the Jameco catalog, I found the next list stated as an inverting buffer with the number 8287. I believe this may be the same as the 8303 that I've been looking for. Can anyone tell me what the pinout is for either a i8287 or a uPD71087 ?? Thanks Dwight
