Date: 19950708 From: hubbardm Newsgroups: sci.electronics Subject: 741 Pinouts needed I don't have my data books at home either. This is from the back of a Radio Shack 741 blister pack. 1. Offset Null 2. Invert Input 3. Non-Invert Input 4. V- 5. Offset Null 6. Output 7. V+ 8. NC Date: 19950712 From: Karel Hladky Newsgroups: sci.electronics Subject: 741 Pinouts needed As regards the: : 741 : Universal operational amplifier. : : +---+ +---+ : NULL |1 +--+ 8| : -In |2 7| VCC : +In |3 741 6| OUT : VEE |4 5| NULL : +----------+ It had always puzzled me why pin 5 is used for offset, instead of the more convenient (from the point of view of PCB design) pin 8. Why are we stuck with this seemingly illogical standard? Any ideas, anyone? Karel ++++++++Manchester M14 6BF England++++++++
