The characteristics of NE555 are as follows: 1. A simple resistor and capacitor can be used to complete a specific oscillation delay. The delay range is extremely wide and can range from a few microseconds to a few hours. 2. It has a large operating power range, and can be matched with logic gates such as TTL and CMOS, that is, its output level and input trigger level can be combined with the high and low states of these logic series. 3. The output current of the output terminal is large, which can directly push a variety of automatically controlled loads. 4. It has high timing accuracy, good temperature stability and low price.
