NE555P Timer Delay Pulse Generation Oscillator IC – Reliable with 8 Pin DIP Sockets

Product Information

The NE555P is a precision timing circuit that can produce accurate time delays or oscillation. In delay or monostable operation mode, the time interval is controlled by a single external resistor and capacitor network. In astable operating mode, frequency and duty cycle can be independently controlled using two external resistors and one external capacitor.

The threshold and trigger levels are typically two-thirds and one-third of VCC, respectively. These levels can be changed by using the control voltage terminal. When the trigger input is below the trigger level, the flip-flop is set, and the output goes high. If the trigger input is above the trigger level and the threshold input is above the threshold level, the flip-flop is reset, and the output is low.
