NE555N Precision Timer IC DIP-8 Oscillator Delay Circuit

The NE555N is one of the most widely used timer ICs in electronics, available in a DIP-8 package. It operates in monostable (one-shot) and astable (free-running oscillator) modes, making it ideal for a vast range of timing, delay, and pulse generation applications.

Key Specifications:

• Package: DIP-8
• Supply Voltage: 4.5V – 16V
• Output Current: Source/Sink up to 200mA
• Timing: Controlled by external R and C components
• Trigger/Reset: Falling edge triggered
• Temperature Range: 0°C to +70°C (NE grade)
• Variants available: Original & China grade

Operating Modes:

• Monostable: Single pulse output with precise time delay set by one resistor and one capacitor
• Astable: Free-running oscillator with frequency and duty cycle set by two resistors and one capacitor

Applications:

• PWM signal generation
• LED flashers and tone generators
• Delay and debounce circuits
• Frequency dividers
• Arduino and DIY electronics projects
