Need to find 74OL6010 Optocoupler

Postby KJ8CQ » Wed Jan 02, 2008 6:27 pm

Hello everyone.

Looking for a source on the 74OL6010 Opto-couplers. Saw these on Steve (QIX) website as he used them in his PWM modulator circuit. Went looking for them at Digikey, Mouser & Newark and none of these suppliers stock them any longer. Looks like this part may have been discontinued.

What is everyone else using as an Opto-coupler between their PWM generator and PWM modulator.

I do have some 6N137 on hand that I could use, however, I would still need a level converter to drive the TC4421’s (which I have on hand as well).

Any suggestions would be appreciated.

Thanks

Geez, I'm not sure... I got mine from Digikey (2 years ago)...

First thing I'd do , is email Steve, QIX, and ask if he has any...

Worth a shot..

Thank you for the response it is appreciated.

I took your advice and attempted to email Steve. Had three different email addresses and two have come back undeliverable, not sure yet if the 3rd email made it through or not.

I suppose there’s a good chance Steve will wander past this posting and respond.

Thanks

Steve,

Just because they do not have them in stock doesn't necessarily mean they are no longer available. Fairchild doesn't list them as discontinued.

I'd try ordering it, and see what happens.

I checked with Fairchild, they list 4 distributors that suppossedly had them... the distributors say they don't.

Fairchild themselves don't have any for sale either... they say "not available"

I'm sure someone, somewhere has them, but might need to shop around for a suitable replacement...

I would think anything rated for the same speed, input voltage, and output current would work fine..

I found them!

I was able to locate a few of these, however, the supplier is located in the UK. The company name is Farnell Electronics and they show an inventory of about 1000 pieces. Beware, Farnell has a minimum order of (21.00 Pounds Sterling) for credit cards and the shipping is a little hefty as well. I don't know the exact exchange rate but figured it was about 2:1 so the order is about $45.00 US

http://WWW.Farnell.com

I ordered a few other parts that I needed just to make the minimum.

Thought I would post here just in case anyone else had been looking.

Thought I would post this information just in case anyone else was considering picking these up from Farnell.

I placed my order with Farnell in the UK on Monday January 7th and amazingly my packaged arrived on Friday the 11th. The total cost for the 21.00 pounds was $42.73 US and they didn’t charge me shipping.

One other note, when I located these, Farnell had 1300 in stock. By the time I placed my order the stock level had dropped too about 1000. Just checked Farnell inventory today and there are less than 500 remaining.

Thanks

Stu,
Steve WA1QIX has some of these.

He is still packaging these with the pwm generator kits.

I have a reasonable supply of these parts - both the 10 and 11 versions (inverting and non-inverting).

Regards,

Steve
