 		 #162487 - Yes, more than one type of SIL network
Responding to: ???'s previous message

If you buy a 8-resistor (9-pin) SIL resistor you will have eight resistors all wired together on one side.


As I mentioned before, not all SIL resistor packs are wired this way: some have individual resistors; some have them connected in series, etc, etc...

Yes, there are n+1 SIL networks where all n resistors are connected in series too, and SIL networks with two groups of resistors or with individual resistors:

There are probably other variants in existence to, so you have to check twice before buying. But they are nice since they are small and results in fewer solder points.

            Hence the reason...            01/01/70 00:00      
               I do not think so            01/01/70 00:00      
                  His "please explain" thread proves...            01/01/70 00:00      
                     cant u?            01/01/70 00:00      
                        You need to provide            01/01/70 00:00      
                        Do you mean this?            01/01/70 00:00      
                           Thanks Sir KAi            01/01/70 00:00      
                              10K SPI            01/01/70 00:00      
                                 Meaning of "SIP"            01/01/70 00:00      
                                    A 10K SIP Indeed !!!            01/01/70 00:00      
                                       How it works??            01/01/70 00:00      
                                          Short for what            01/01/70 00:00      
                                          Look again - and think!            01/01/70 00:00      
                                       so, what he has used?            01/01/70 00:00      
                                          Why more schematics?            01/01/70 00:00      
                                             But            01/01/70 00:00      
                                                10k SIP do not connect anything. They add something!            01/01/70 00:00      
                                                   what for 8051            01/01/70 00:00      
                                                      do you EVER bother to read the docs before asking questions            01/01/70 00:00      
                                                         Back to basics            01/01/70 00:00      
                                                      Yes, you will            01/01/70 00:00      
                                                RE: how those eight data lines are connected ?            01/01/70 00:00      
                                             But            01/01/70 00:00      
                                                as seen on the schematic            01/01/70 00:00      
                                             Not all SIL resistor packs are the same!            01/01/70 00:00      
                                                Yes, more than one type of SIL network            01/01/70 00:00      
                              looks exactly like what I would suggest            01/01/70 00:00      
                              Both, but take care...            01/01/70 00:00      
                                 what you think about this?            01/01/70 00:00      
                                    Post link            01/01/70 00:00      
                                       No no            01/01/70 00:00      
                                          Doesn't add up            01/01/70 00:00      
                                    Depends...            01/01/70 00:00      
                              it wont worked....            01/01/70 00:00      
                                 Still Doesn't add up!            01/01/70 00:00      
                                 Then you have done something wrong!            01/01/70 00:00      
                                    experimenting "wildly" ....            01/01/70 00:00      
                                       Basic electronics            01/01/70 00:00      
                                    You are right...            01/01/70 00:00      
                  Actually            01/01/70 00:00      
      Please explain            01/01/70 00:00
