I'm trying to figure out the differences between the 4000 series and 7400 series IC's. I know the 4000 are CMOS, have been around longer, use less power, but are slower. The 7400 series are TTL, newer, faster, but use more power.
But then the 7400 has low power 74LS00 versions and CMOS compatible 74HC00 versions. It all seems very confusing to pick the right type. I want to build up an on-hand inventory of various chips but am not sure what to buy.
So what are people actually using in new circuits today? Does it still just depend on the speed required of the circuit and if it's battery powered or not? What do you guys typically use and why?
