I think if any possible, there should be some of these common parts on the market at affordable price, if old inventories exist. Apr 3, 4. Why counterfeit there’s plenty genuine old IC?
Datasheeg Current Consumption, Smaller Footprints: The ICS I’ve shown are quite skuffy means there are bits chipped off from corners and who seriously wants datashset counterfeit these kind of IC? Apr 3, 8. Apr 3, 6. Apr 5, Posted by Detonator in forum: Some more posts I put the ICs in a single row each and hope at least a few can become possible to descrbe All silicon chips have some ppm duds over time you get failures if the ICs are not factory fresh most likely there will be more failures.

Apr 2, 2. S, design, not subject to production testing. As a practical joke?
Ok but there have been and there it datxsheet countless different places of IC fabrication often dies are not packed immediately at place of die production and in your pictures there’s a lot variation it’s like you say what you have on hands is all possible variation? As well the mentioned faulty EPROMs i was able to catch up on these before they made way to customer I don’t datadheet collectors prices so what counts is if the die is genuine aka the IC works.
Here is the datapage.

And yes i have tms which i believe have been refurbished with a fresh logo. My idea is to try the oscillator pins probably at different pins for different ICs And many others. Theres not just China I have stopped reordering from china bcz the long waiting basically its like using a credit line its like I need to pay first and it could be several months just for the first sale.
