NE555 chip

NE555 chip - is an analog integrated circuit - a device for the formation (generation) of single and repetitive pulses with stable timing.

Datasheet on NE555 chip .

IC consists of a voltage divider with two reference voltages for comparison, two precision comparators (low and high), RS-trigger with additional input reset transistor switch with open collector output of the power amplifier for increase in load capacity.

Conclusion NE555 chip :

• GND - common ("minus" power);
• TRIG - start;
• OUT - output;
• RESET - reset;
• CTRL - control (control divider);
• THR - stop;
• DIS - discharge;
• VCC - power ("plus" power).
