NE555/ICM7555/ICL7555/TLC555 Pin out

These chips are 8-pins packaged timers and can be operated by 2v to 16V. The NE555/ICM7555/ICL7555/TLC555 have the same pin out. They are all the same integrated circuits (IC) and have the same pins configurations. The difference between these integrated circuits is the manufacturer of the IC. NE555/ICM7555/ICL7555/TLC555 pin outs and functions of each pin

THE TYPES OF CAPACITOR

There are many different types of Capacitor. In general, they fall under one of these categories: Polarized Capacitor Non-Polarized Capacitor Variable Capacitor POLARIZED CAPACITORS Polarized capacitor types of capacitor must be connected correct way otherwise, will be damaged if connected wrongly. At least one of their leads (terminals) is mark either “+” or “−”.  Examples
