Post by thread:[EE]: multi opto coupler

Did a web search but couldn't find what I was looking for. I need some opto-couplers with multiple optos in one small DIP package. Pref four units, but two or three would be ok. A perfect unit would have 6 optos in a 14pin dip, but maybe i'm dreaming here. Has anyone used these or know where to source? :o) -Roman -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.

Try the NEC PS2501 opto's they are in a 4 pin package and are available in blocks of 4 PS2501L-4 (16 pins). If you want, there is a 16 pin ssop package with 4 opto's PS2801L-4 http://www.ic.nec.co.jp/opto/english/document.html {Quote hidden}>Did a web search but couldn't find what >I was looking for.

I have just tested one. It was given to me by a friend of mine this morning it only has 817 on the top ( 4 pin ) When used with s 10k pull up on the transistor side it just works fine. I drove the diode thro 270ohm resister from 16F877. It was to drive a power MOSFET. {Original Message removed}

Thank you! I will look into these. :o) -Roman Ray Gardiner wrote: {Quote hidden}> > Try the NEC PS2501 opto's they are in a 4 pin package and are available in > blocks of 4 PS2501L-4 (16 pins).

The ILQ74-2 (dual) & ILQ74-4 (quad) should be easy enough to get in Oz. I bought the last lot from Avnet but we (& a lot of others) don't deal with them since their "policy changes" came into place. (I think Farnell had them for not too bad a price from memory) The PC817 is confusing as a some suppliers (WES) have them as single, dual & quad units but don't really show that in the price list. The ILQ74-4 is in a DIP16 package.

The WES option sounds the best yet. We order about twice a week from them. I will give them a ring! Thanks. -Roman -- http://www.piclist.com hint: The PICList is archived three different ways.

Farnell list 7 types from Vishay, TI, Toshiba & Siemens for std transistor output. Also 2 AC input and 4 darlington outputs. All quads in DIP.

Dear Roman, The PC817 is a 4 pin single device. The PC827 is a dual 8 pin and the PC847 is quad 16pin. They are all marked with pc817 on the case - the pc827 twice and the pc847 four times. About 35c per opto from Manuco Electronics, Victoria. Regards,Kresho. > {Original Message removed}

Not sure what the largest number you can get, but you can see they saw them off to make singles, duals, quads. -- http://www.piclist.com#nomail Going offline?
