CHAPTER 13
Timer, CMOS, and Motor Drive Circuits
We will be looking into analog timing and oscillator circuits that use the NE555/LM555 (a.k.a., 555 circuit or chip) integrated circuit. Although this circuit was manufactured in the early 1970s, it still finds many uses in hobbyist circuits and projects. The 555 circuit is an 8-pin integrated circuit that can be configured into many different circuits. For example:
• A timing circuit to provide a fixed duration pulse when triggered by an external signal (e.g., closing a switch). The 555 can be configured as a one-shot circuit to generate pulses.
• 555 oscillator circuits.
• A simple CMOS ...
