Good afternoon , all right?

I wonder if there is no way to add a component in the VP- 798 list.

Or rather, other developers will not have this component in the lists , the research I"ve done on the site .

The component is PALC16L8-25PC and PALC16L8-35PC Cypress .

VP-390 Fails When Programming M27C160 Reply  
I have a VP-390 running on Windows 10 on software 4.7.0 and firmware version 17.0.

I have been trying to program ST M27C160 chips, and it always fails after writing a few bytes. I have made sure to Select the chip model in the software before trying to program the chip. I have tried 15 different chips and all of them have failed. They all pass the Blank Check and I can successfully Read the chips. Other types of chips are programming just fine - only the M27C160 chips fail.

Any advice?

CMOS/TTL testing Reply  
Using the VP390 to test logic ICs, the test for CMOS 4503, 4508 do not work, even with brand new devices.
the problem is with the tri-state output. The VP390 does not appear able to consistently test for a
high-impedance output.

Can anyone confirm that this is not just my VP390, but a general design or pattern problem, and is there
any way of testing for Hi-Z outputs or two-supply (level-shifter) devices?
