Recommended IC testers?
« on: January 11, 2019, 06:41:10 am »
Hello,
I need to test some IC's like flip-flops and 32kb / 64kb RAM chips.
Is something like this what  i need to determine if they are problematic?

Thanks in advance!

ICs are so diverse, which means that there isn't really going to be any general purpose tester (at least not to my knowledge ... if there is, I don't expect it to be cheap and if it is cheap, I can't see it being particularly useful).

The best suggestion I can offer is to make up a circuit that uses a given IC and try each chip (using a socket) to see how it operates.  If you have different operating conditions, then have them set up and switch between configurations to see how it works.

For the logic chips, there may be some "testers", though there main purpose would be more like EPROM programming. So it more like a universal programmer for EEPROMs and the like, that can also test standard (e.g. TTL, 3 / 5 V CMOS) logic.

For most other chips I am with Brumby - build a test board for that specific chip.

For OPs there might be a certain sense to have one around - as they are common and relatively easy to check.
For an OP I would use something like a x 100 amplifier from a switchable impedance ground. So one could test thinks like offset, bias and maybe noise, besides the basic go / no go test. It would also need a suitable supply choice (e.g. 5 V or some maybe 12 V, as some OPs are 5.5 V max. and others could be 8-10 V minimum).
