74135 datasheet pdf

Apr 28, 3, I plan to ask about several IC here Starting with the TMS I have several etc simple controllers just no type number these are for televisions with OEM house number, anybody who could test these? My idea is to try the oscillator pins probably at different pins for different ICs And many others. Apr 2, 2. Apr 2, 3. A few more obscure kinds in the pipeline Apr 3, 4.

Apr 5, 18, 3, Here is the datapage. Apr 3, 7.

Apr 3, 8. Apr 3, 9. Apr 3, Apr 4, One other thing I noticed is that the markings on the Motorola parts I checked, none of them had the logo by the date code: Ok but there have been and there it has countless different places of IC fabrication often dies are not packed immediately at place of die production and in your pictures there’s a dxtasheet variation it’s like you say what you have on hands is all possible variation?

The ICS I’ve shown are quite skuffy means there are bits chipped off from corners and who seriously wants to counterfeit these kind of IC? As a practical joke? It’s not even worth low-cost labour not to speak profits a fake IC most likely simply has no die or a too small die for a high power part and there are just a few known occurances such as empty main board cache IC These days it’s often cob for cheap ic. Apr 5, NASA report now you’re kidding me i dafasheet most of the images easy prey via Google search.

Why counterfeit there’s plenty genuine old IC? And yes i have tms which i believe 71435 been refurbished with a fresh logo.

As well the mentioned faulty EPROMs i was able to catch up on these before they made way to customer I don’t charge collectors prices so what counts is if the die is genuine aka the IC works. I will study these.

Another one SN or with P2 suffix SN Mostly the older IC kinds come from desolate inventories which have been scrapped and sold off, mostly ICs for products no longer manufactured but also all kinds of stockpiles no longer needed. 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.


Many of these IC are not longer needed or theres just not many potential buyers interested in them. The is not so special actually and not particulary powerful but people get nostalgic feelings including me.

I think if any possible, there should be some of these common parts on the market at affordable price, if old inventories exist.

Theres no point hoarding old ICs and asking for moon prices and wait until the epoxy becomes datwsheet. 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.
