NE555 is mainly characterized in that:

1. the simple resistor of a need, capacitor, can complete specific oscillation delay effect.Its reference time delay is extremely wide, can be by several microseconds to several hours as long as.

2. its operation power range is very big, can be with TTL, and the logic circuit such as CMOS coordinates, namely its output level and input triggering level, all can be with the high and low level match of these logical series circuit.

3. the supply electric current of its outfan is big, can push directly on the multiple load automatically controlled.

4. its timing precision is high, temperature stability is good, and low price.

The pin relation of NE555 and function are as follows:

Pin 1 (ground connection)-ground wire (or common ground), is typically attached to circuit common ground.

Pin 2 (trigger points)-this foot position is to trigger NE555 to make it start its time cycle.Triggering signal upper limb voltage must be more than 2/3 VCC, and lower edge must be less than 1/3 VCC.

Pin 3 (outputs)-start the output pin position of 555 when the time cycle, move to the high potential of few 1.7 volts than supply voltage.The output that terminates in cycle returns to the electronegative potential about O volt.Maximum output current when high potential about 200mA.
