{"title":"555/556 Timer - NE555P","handle":"555-556-timer-ne555p","url":"/products/555-556-timer-ne555p","description":"The NE555 is one of the most iconic and widely used integrated circuits in electronics history. Designed in 1971 by Hans Camenzind, it provides configurable timing and oscillation using just a few external resistors and capacitors. Available here in both single (555, PDIP-8) and dual (556, PDIP-14) packages.\n\nIn time delay (monostable) mode, the output pulse duration is set by one external resistor and capacitor. In oscillator (astable) mode, the frequency and duty cycle are controlled with two resistors and one capacitor. The DIP package drops straight into breadboards and perfboards for easy prototyping.\n\nKey Features\n\n\nMultiple Operating Modes – Astable (oscillator), monostable (one-shot), bistable (flip-flop), and inverting buffer\n\nWide Supply Range – 4.5V to 16V operation\n\nHigh Output Current – Up to 200mA source/sink (555) or 150mA (556)\n\nBreadboard Friendly – Standard DIP package for easy prototyping\n\nDual Package Available – 556 contains two independent 555 timers sharing power pins\n\n\nOperating Modes\n\n\nAstable – Generates a square wave of configurable frequency\n\nMonostable – Produces a single pulse of configurable duration on trigger\n\nBistable – Output depends on two input states (flip-flop)\n\nInverting Buffer – Output is the inverse of the input\n\n\nSpecifications\n\n\nSupply Voltage: 4.5–16V\n\nMax Frequency: 100kHz\n\nSupply Current: 2mA (555) / 4mA (556)\n\nOutput Current: 200mA source/sink (555) / 150mA (556)\n\n555 Package: PDIP-8\n\n556 Package: PDIP-14\n\n\nIdeal For\n\nLED flasher and blinking circuits\nTone and sound generation\nPWM motor speed control\nTiming delays and pulse generation\nLearning analogue electronics fundamentals\n\n\nResources\n\nNE555P Datasheet (PDF)\nNE556N Datasheet (PDF)\n","vendor":"Pimoroni","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":7732,"title":"Default Title","sku":"PI-COM0207","price":1.2,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
