The Ultimate Guide to NE555N VS NE555P

 

Overview of NE555N and NE555P

 

The NE555 is a highly stable IC in which the time delay and/or oscillation can be controlled with external resistors and capacitors. This chip was first made commercially available by Signetics in 1972. It is well suited for a variety of applications such as a timer or pulse generator.

NE555N vs NE555P

The NE555N and NE555P are essentially the same ICs with the main difference being the packaging:

NE555N:

  • Packaged in a plastic DIP (Dual In-line Package).
  • The PIN count for this package is 8. This is to be used in through-hole soldering.

NE555P:

  • Also packaged in a plastic DIP.
  • Has the same 8 PIN count.
  • To be used in through-hole soldering.

The "N" and the "P" don't signify any difference in the operation of the NE555 timer itself. They might only indicate a minor procedural or material change in the manufacturing process depending on the manufacturer. The two types can be used interchangeably in a circuit, and they share identical performance characteristics.

Features of NE555 Timer:

  • Direct replacement for SE555/NE555.
  • Timing from microseconds through hours.
  • Operates in both astable and monostable modes.
  • Output current can source or sink 200 mA.
  • Adjustable duty cycle.
  • TTL compatible.
  • Temperature stability better than 0.005% per degree Celsius.
  • Usually, supply voltage in the range 4.5V to 16V.

Applications of NE555 Timer:

  • Precision timing.
  • Pulse generation.
  • Time delay generation.
  • Pulse width modulation (PWM) circuits.
  • Sequential timing.
  • Missing pulse detection.

Despite being an old chip, the NE555 timer is still widely used due to its reliability, versatility, and cost-effectiveness. Always refer to the manufacturer's datasheet for precise details.

 

NE555N vs NE555P: Differences

The NE555N and NE555P are both versions of the NE555, a common and versatile timer IC. This integrated circuit can be used for a variety of applications, including timing, pulse generation, and oscillation tasks.

"N" and "P" in the part name, NE555N and NE555P, most often refer to the type of package and material used for the IC. Both NE555N and NE555P come in plastic, Dual-In-Line Package (DIP), and are typically designed for through-hole mounting on the printed circuit board.

As of my last training data in September 2021, those designations do not suggest any functional, performance, or quality differences between the chips. Both ICs are identical electronically, with the same pinouts and operational characteristics.

However, different manufacturers may have individual ways to name their products or versions of it, so it's possible there may be some variations between specific NE555N and NE555P parts from some manufacturers. Always consult the manufacturer's datasheets or other documentation for specific details in order to understand the exact specifications, capabilities, or any other particularities.

 

NE555N vs NE555P: Similarities

 

The NE555N and NE555P integrated circuits share a substantial number of similarities, as they are essentially the same device but may come in slightly different packaging or from different processing batches. Here's a rundown of their commonalities:

Functionality:

  • Both are timers that can be configured in astable or monostable modes for a variety of applications like pulse generation, timing, and delay.
