( Brand: Signetics ), ( Manufacturer Part Number: NE556N ), ( Part Type: Timer )
The Signetics NE556N is a dual timer integrated circuit (IC) in a DIP-14 package. This iconic chip, which is a part of the 555 timer IC family, is widely used for various timing applications due to its versatility and ease of use.
Each NE556N chip contains two independent astable multivibrator timer circuits, which can be used to generate precise time delays or oscillator frequencies. The astable multivibrator mode allows the timer to oscillate between its threshold and trigger voltage levels without the need for an external clock input. This makes the NE556N ideal for applications where a stable time delay or frequency is required.
The NE556N is designed with adjustable frequency and duty cycle capabilities through external components. The frequency of oscillation can be controlled by setting the values of external resistors and capacitors connected to the timer's control pins. The duty cycle, or the ratio of the high time to the total cycle time, can also be adjusted by changing the values of these external components.
The NE556N is a monolithic IC, meaning that all the necessary components for the timer function are integrated on a single silicon chip. This not only simplifies the design of the circuit but also improves the reliability and stability of the timing function.
The DIP-14 package of the NE556N contains 14 pins, which are labeled to indicate their functions. The power pins (VCC and GND) are used to supply power to the chip, while the control pins (TRIG, RESET, and THRESHOLD) are used to set the operating mode and timing characteristics of the timer. The output pins (Q and Q*) provide the timing signal, which can be used to drive other circuits or devices.
The NE556N is suitable for a wide range of applications, including timing circuits, oscillator circuits, pulse generation circuits, and pulse width modulation (PWM) circuits. It is also commonly used in hobbyist projects, educational circuits, and industrial control systems.
In summary, the Signetics NE556N is a versatile and widely used dual timer IC in a DIP-14 package. Its ability to generate precise time delays and oscillator frequencies through adjustable external components makes it an essential component for various timing applications.
