NE555 Schmitt Trigger

How a NE555 Schmitt trigger works. The NE555 can be used as a Schmitt trigger by using the two comparators in the chip to make a Schmitt Trigger. Using the NE555 as a Schmitt Trigger Schmitt Triggers Simply put a Schmitt trigger is an electronic circuit designed to detect a voltage crossing point, then produce … Continue reading NE555 Schmitt Trigger

555 Astable Mode

In the 555 astable mode, the IC puts out a continuous stream of rectangular pulses having a specified frequency. 555 Astable Mode Resistor R1 is connected between Vcc and the discharge pin (pin 7) and another resistor (R2) is connected between the discharge pin (pin 7), and the trigger (pin 2) and threshold (pin 6) … Continue reading 555 Astable Mode

555 Monostable Mode

In 555 monostable mode the chip produces a one-shot output pulse. Uses include triggering other processes, timers, alarms, even another pulse generator. Another application is use of a monostable is to clean up incoming pulses. 555 Monostable Mode Description In monostable mode the 555 timer outputs a high pulse, which begins when the trigger pin … Continue reading 555 Monostable Mode
