Re: 74LS90, 74LS92 and other TTL are OBSOLETE???

Yes of course it can be replaced by a uCU... or a CPLD, FPGA, ASICs,
etc!
The question is, WHY to replace a simple <10cents Ic with a >1$ (+ cost
to make the code) one to do the job??? if you just need to do only the
ting the TTL logic does?
Do they going nut (IC makers) or ... ?
