{"title":"555/556 Timer - NE556N","handle":"555-556-timer-ne556n","url":"/products/555-556-timer-ne556n","description":"The NE556N is a dual timer IC containing two independent 555 timers in a single PDIP-14 package. Both timers share common power and ground pins but operate completely independently, making it ideal for circuits that need two timing or oscillation functions without the board space of two separate 555 chips.\n\nEach timer supports the same operating modes as the classic 555 — astable (oscillator), monostable (one-shot), bistable, and inverting buffer — controlled by external resistors and capacitors.\n\nKey Features\n\n\nDual Independent Timers – Two complete 555 timers in one 14-pin DIP package\n\nMultiple Operating Modes – Astable, monostable, bistable, and inverting buffer per timer\n\nWide Supply Range – 4.5V to 16V operation\n\n150mA Output Current – Source or sink per timer output\n\nBreadboard Friendly – Standard PDIP-14 package\n\n\nOperating Modes (per timer)\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: 4mA (total for both timers)\n\nOutput Current: 150mA source/sink per timer\n\nPackage: PDIP-14\n\nTimers: 2× independent\n\n\nIdeal For\n\nCircuits requiring two independent timing functions\nSequential timing and pulse generation\nDual oscillator and tone generation\nSpace-constrained designs needing two 555 functions\n\n\n\nTip: Only need one timer? See the NE555P single timer (PDIP-8).\n\n\nResources\n\nNE556N Datasheet (PDF)\n","vendor":"Pimoroni","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":7739,"title":"Default Title","sku":"PI-COM0208","price":1.88,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
