Description Regular price Student discount
An easy-to-use design program for the popular 555 Timer. Quickly explore and prototype many designs. Allows a "cut and try" method so that an engineer can try a wide range of possibilities in a very short time. EZ-555 allows users to change timing resistors, timing capacitor, frequency and duty cycle. Change one or several parameters at a time. Choose re-calculate to graphically see your results. Changing the duty cycle recalculates R1 and R2. Changing frequency recalculates the timing capacitor. An excellent analysis and design tool for engineers, students, and educators.
