Since the last post i have read the guide at http://www.pinrepair.com/begin/index.htm#howdmm on how to test chips.

From what i understand put the red lead of mm on the GND pin of the chip and all the rest (except PWR) should read between 0.4 and 0.6V if i read the guide correctly...

After doing this, on both the IC15 and 16 i got a range of readings - most around 3V, some 4.8 and some 0.

Did i do this right and/or is the chip faulty?

Thanks
