Hello, I have an IC I want to identify. Here's the problem. I have a machine that uses a Xenon pulsed arc light, the markings have been ground off by the vendor of the machine. The ic is mounted on a small pcb with a four pin connector and to be replaced when the bulb is replaced to reset a use counter. The IC appears to be used to count the bulb usage somehow and trigger an indicator when the bulb needs to be replaced. The (non US) machine vendor is no longer in business and I can't get the ic board anymore. The bulbs are std and readily available so I want to either reset or replace the ic board.
The IC is an 8 pin DIL with a semicircle notch at one end. With semicircle marker at the top, all the left hand (four) pins and pin 2 down from the marker on the right side are wired together and onward to one of the connector pins. The remaining three pins on the right, 1,3,4 down from the semicircle marker each go to one of the remaining pins on the connector.
I've not yet opened up the machine to see what the board connects to.
Any ideas appreciated..
