SN74F86DR

The SN74F86DR is a quad 2-input exclusive OR (XOR) gate integrated circuit (IC) manufactured by Texas Instruments. It is part of the SN74 series of logic devices, which are known for their high-speed performance and low power consumption. Here’s a detailed description of the SN74F86DR:

General Features:

• Functionality: The SN74F86 contains four independent 2-input XOR gates. Each gate performs the exclusive OR operation, which outputs a high signal (logic 1) when the number of high inputs is odd.
• Technology: It is built using advanced bipolar technology, which allows for fast switching speeds and improved performance in digital circuits.
• Speed: The device operates at a maximum propagation delay of around 5 ns at a supply voltage of 5V, making it suitable for high-speed applications.
• Power Supply: The SN74F86DR operates with a supply voltage range of 4.5V to 5.5V, making it compatible with standard TTL (Transistor-Transistor Logic) levels.

Pin Configuration:

• The SN74F86DR is available in a 14-pin Dual In-Line Package (DIP) or a surface-mount package (SOIC). The pin configuration includes:
  • Inputs: Each XOR gate has two inputs (A and B).
  • Outputs: Each gate has a corresponding output (Y).
  • Power and Ground: The IC has dedicated pins for power supply (Vcc) and ground (GND).

Electrical Characteristics:

• Input Voltage Levels: The input high voltage (VIH) is typically around 2.0V, while the input low voltage (VIL) is around 0.8V.
• Output Voltage Levels: The output high voltage (VOH) is typically close to Vcc, and the output low voltage (VOL) is close to ground.
• Current Consumption: The device has a low quiescent current, making it energy-efficient for battery-operated devices.

Applications:

• The SN74F86DR is widely used in digital logic circuits, including:
  • Arithmetic operations in adders and subtractors.
  • Data comparison and parity checking.
  • Implementing complex logic functions in programmable logic devices.
  • Signal processing applications where XOR operations are required.

Packaging:

• The "DR" suffix in the part number indicates that the device is available in a surface-mount package, specifically the SOIC (Small Outline Integrated Circuit) package, which is suitable for automated assembly and provides a compact footprint for circuit designs.

Summary:

The SN74F86DR is a versatile and high-performance quad 2-input XOR gate that is ideal for a variety of digital logic applications. Its combination of speed, low power consumption, and ease of integration makes it a popular choice among engineers and designers in the field of electronics.
