SE555D +BOM

Precision timer for -55 to 125C operation

SE555D Information

Description

The TI SE555D is a type of timer/oscillator IC, specifically a 555 timer IC, designed for single operation. It offers an adjustable timing range from microseconds to hours, with the ability to function in either astable or monostable modes. The device provides an adjustable duty cycle and outputs a TTL-compatible signal that can sink or source up to 200mA. This component is suitable for applications where precise timing and oscillation are required, such as in digital circuits, alarm systems, and instrumentation. The SE555D's versatility, reliability, and small package (8-SOIC) make it a popular choice for designers and engineers in various industries.

Features

The SE555D features include:

  • Timing from microseconds to hours
  • Astable or monostable operation
  • Adjustable duty cycle
  • TTL-compatible output that can sink or source up to 200mA

These features make the SE555D a versatile timer/oscillator IC suitable for various applications.

Package

According to the product information, the package type of SE555D is an 8-SOIC (0.154", 3.90mm Width).

Pinout

The SE555D has an 8-pin SOIC package. Regarding the pin functions: 1. Vcc (Pin 3): Positive voltage supply. 2. Trigger Input (Pin 6): Sets the timing period, in relation to the threshold input. 3. Threshold Input (Pin 5): Determines the time when the output transitions from low to high. 4. Reset Input (Pin 4): Resets the timer to its original state. 5. Output (Pin 1): The timer's stable output signal. 6. Stable/Unstable Output (Pin 2): Signals whether the output is in an astable or monostable mode. 7. GND (Pins 8 & 0): Ground connections. The SE555D does not have a separate pin for Pin 1, as it's implied to be the same function as Pin 2.

Manufacturer

The manufacturer of the SE555D is Texas Instruments (TI), a well-known American technology company that designs, manufactures, and sells semiconductors and related products. TI is a multinational company with a wide range of products and applications in industries such as industrial automation, aerospace, automotive, medical devices, and more.

Applications

The SE555D timer IC is a versatile component suitable for various applications. Typical usage includes:

  • Timing control in digital circuits
  • Pulse modulation and shaping
  • Sine wave generation
  • Frequency counters
  • Clock generators
  • Power-up sequencing systems
  • Timer-controlled motor controllers

These are general examples of application areas, but the actual use case depends on the specific design requirements.

Equivalent

The equivalent products of SE555D are:

  • NE555
  • LM555
  • MC1455B
  • SA555D

These ICs are all variants of the classic 555 timer chip, offering similar functionality and specifications to the SE555D.
