| Market Reality | Fifty years after introduction the 555 is still designed in, still taught, and still repaired. The bipolar NE555 remains in mass production across several fabs, so availability is not the issue. The two things that matter are the bipolar-versus-CMOS family boundary - the pinout survives the crossing but the output drive does not - and sourcing lots whose timing and temperature specifications are real; the 555 is a favorite of low-grade clones where timing accuracy is the first spec quietly loosened. | Fifty years after introduction the 555 is still designed in, still taught, and still repaired.
