Apr 4, Discussion in ‘ Electronics Resources ‘ started by takaoApr 1, 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 lot variation it’s like you say what you have on hands is all possible variation?

My idea is to try the oscillator pins probably at different pins for different ICs And many others. Apr 5, 18, 3, Wouldn’t upload in previous post Lower Current Consumption, Smaller Footprints: Apr 2, 3.

Posted by Detonator in forum: One other thing Datashet noticed is that the markings on the Motorola parts I checked, none of them had the logo by the date code: Mar 30, 7, 1, Apr 3, Theres no point hoarding old ICs and asking for moon prices and wait until the epoxy becomes brittle.

Request thread for very old ICs (cant find datasheet)

You May Also Like: Apr 3, 8. Here is the datapage. 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? Theres not just China I have stopped reordering from china bcz the long 7415 basically datasheeh like using a credit line its like I need to pay first and it could be several months just for the first sale.

datashet Posted by ian field in forum: I think if any possible, there should be some of these common parts on the market at affordable price, if old inventories exist.

Apr 5, Apr 2, 2. 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. Can’t find an old thread Apr 3, 6.


The is not so special actually and not datasheett powerful but people get nostalgic feelings including me. 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.

Datasheet, PDF – Alldatasheet

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