555 Timer
Discontinued
The classic 555 timer/oscillator IC from Texas Instruments — one of the most versatile and widely used integrated circuits in electronics. With just a few external resistors and capacitors, it can generate timing delays from microseconds to hours, produce square wave oscillations, and drive LEDs, buzzers, or relays directly from its output.
Key Features
- Wide Supply Range – 4.5V to 16V operation
- Astable & Monostable Modes – Oscillator or one-shot pulse operation
- Adjustable Duty Cycle – Control on/off timing with external components
- 200mA Output – Source or sink current, TTL compatible
- Timing Range – Microseconds to hours
- 8-Pin DIP Package – Breadboard and perfboard friendly
Specifications
- Supply Voltage: 4.5–16V
