Self-Correction Design Based on Twisted Ring Counter 74LS161
Lun Shu-xianb · Journal of Jilin University · 2011
The self-correction is designed based 74LS161 twisted ring counter,aiming at exploring logic modification technique of MSI(Medium Scale Integrated circuit) programmable counter by unconventional use of changing the application direction,that is to change the counting rules by changing the logic output state of programmable counter 74LS161,achieve the timing relationships ofnext state=setting data by that the state output the feedback to the preset number of inputs and to modify self-correction logic design,achieve the self-correction design of twisted ring counter,thus achieve the logical extensions.The Innovation is to propose the logic modification method of MSI programmable counter changing the application direction,Design progress of twisted ring counter is simplified.
