74161 Datasheet

Message 8 of But, when the second counter’s RCO carries over to the third counters ENT ddatasheet stays high for a long period of time the duration of the QA and sets off the third counter to “race at clock speed” similar to the first counter. This is not the case when connecting to ENP.

I am asking because I found another post in this board that noted that the issue was resolved. They should form a simple 16 datahseet binary counter that keeps incrementing until all of the output bits for E4 are all zeros and then it loads all the counters with preset value. Message 7 of Message 10 of I am especially looking for information concerning the “old 70s design” you want to simulate.

In my search for understanding more I discovered a recent document that had identified an error in the 741661 model related to the counter executing on falling edge of clock, should be rising edge. Thanks for sharing these files over here! Message 3 of Message 9 of I tried to simulate the similar cascade in another simulation tool – and i get the reverse and expeced results; that when RCO is connect to ENT, the carry is forwarded and no “racing” occurs. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.

Message 6 of Unfortunately it did not solve my headache.

Please find attached the multisim model. In the schematics the rco is connected to ENT. The case is not solved – datashret I have now asked the moderator to remove the duplicate.

I am building a simulation of an old 70s design based on s and I have had a lot of trouble getting a set of counters to operate according to my expectations. Thanks in advance for your feedback! When connected to ENT as it appears to be done in the orignal schematics p21, B4 to E4 the third counter starts to race at clock speed when RCO set ENT high as can be seen in the attached simulation screen shot.

Message 5 of Message 4 of Message 1 of Question to the forum: Something wrong with the model?

Fairchild Semiconductor

Message 2 of I appreciate any datahseet. Is the model that is being used in there shareable? Most Active Software Boards: I am new to NI tools and new to the forums.

For some reason i couldnt attach files with my message above, and i cannot post them separately either it appears Can you provide me with the following information to help the troubleshooting? Do you have any information about the simulation tool you are comparing to?
