[Chip Identity?]

So if I wanted to order the TA75393AP chip
where would I get it?

[Chip Identity?]

Thanks MP for that info.

Where did you find that info
I went to embeddedlinks.com (chipdir)
and couldnt find anything there.

Is there another website that you know
about?

Thanks again

Does anyone know what this chip is?
I am trying to find the schematics of it but
cannot find anything on it.
It looks like a 555 timer with 8 pins to it.
But it doesnt say anything like that.

Does anyone know a website or a databook
that they may have and can look up the schematics
for me. Here is the number TA75393AP
Remember it looks exactly like the 555 timer
with 8 pins to it.
Thanks for your help

Yea thanks
can you scan some of those EPE magazines
and forward them to my email

Thanks Kevin.

Hey Kevin how would you test an 'AND' gate chip
with a voltmeter?

Thanks for your help

How would you test an OPAMP?
for ex. the LM324

So what your saying is just hook up the 5 volts to the chip
and I would see a 1 and 0 at the input then with my voltmeter
I would see a 1? Where would I hook up the voltmeter? positive to the output and negative lead to ground?

sorry but I dont follow you exactly.
I have to remove the chip from the board?
or can I just plug the board in and use
that source? How do I establish the highs
and lows? How do I know when one input
is high and the other is low or both? can you
tell me exaclty how to wire it up. Thanks for your help.

P.S. I prefer not to remove the chip from the board
because the board contains many chips and I dont
know which one is bad.

Hi all
I would like to know how to test the logic gates of an IC chip, for instance a 'NAND' gate or an 'AND' gate in a circuit with my voltmeter. I do not have an oscilloscope but my voltmeter is capable of reading the highs and lows of the logic gates. Where do I need to hook up the leads from the voltmeter? Let us use the 74LS00 IC chip (Quad-input 'NAND' gate) as an example. see the picture attached. Any help can be greatly appreciated.
