Recently I discovered that the TTL ICs praised in my books are in reality power hungry, ancient technologies - even the LS variant I have used to make some simple circuits.
I would like you to propose an alternate logic family. I would like the following characteristics:
- DIP package or something suitable for stripboards. NO SMDs.
- wide array of functions.
- low price.
- low power consumption.
- wide array of voltages, suitable for battery operation. 9v could be nice, but 2.4 volts (two NiMH AAs) would be better.
- easy to find.
After a search in the Internet, I am between 4000 and 74HC...
