Hello everybody.

I got a Maxim DS1813 ic for my 6502 reset, but I can't get it to work
I'm using my arduino as the power source for my breadboard computer.
I have the DS1813 pin 2 connected to the Arduino's 5v pin and pin 3 connected to Arduino's ground pin.
Doesn't matter what I do, the reset pin is always sending a LOW signal.
Is it perhaps because I'm using my arduino's power supply (which might not be stable enough?)
What are the chances of getting a faulty one?
Any suggestion would be highly appreciated
Thanks!

I've used the DS1813's in many boards without trouble. Here's a double check of the pinout:



With the flat side of the TO-92 device facing you with the pins down, pin 1 is on the left. The first time I used this, I had the device backwards.

If the Arduino's 5v supply is at least 4.75v, then it should work. if voltage is good and pins are correct, I would replace it.

What happens if you ground and then release the reset line (pin 1 on the DS1813)?

I've never had an issue with these devices as well, so like 8BIT, I suspect that the DS1813 is being powered by the Arduino is a factor.

I did exactly this as well. it took me 5 mins to realise that they are showing the device from the underside and not the top side lol.

Hi guys! Thanks for the replies
Yes, I had it the other way around
But it still didn't work. I tested the ic with my arduino nano and a breadboard power supply, but nothing happened.
Then I tried it with my arduino uno and it worked! That's an original arduino, so maybe the components are superior?
Both my nano and power supply were cheap version from ebay. I wonder if that matters.
Thank you all!
