Features

• Standard IC for timer "555."
• It has a simple internal configuration consisting of a comparator, threshold setting resistor, flip-flop, and timing capacitor discharge circuit, but by adding C and R time constant circuits and selecting the connection of other terminals, various application circuits such as timer circuit (delay ON/OFF circuit) and oscillator can be made.
• I will leave the accuracy to the microcomputer, but the 555 works just by constructing a circuit without a program.
• The supply voltage is also wide. This product is a second source product manufactured by TI.
