SN74AHCT86DBR

The SN74AHCT86DBR is a quad 2-input exclusive OR (XOR) gate integrated circuit (IC) manufactured by Texas Instruments. It is part of the SN74AHCT family, which is known for its high-speed performance and compatibility with TTL (Transistor-Transistor Logic) levels. Here’s a detailed description of its features and specifications:

General Features:

• Functionality: The SN74AHCT86 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.
• Supply Voltage: The device operates with a supply voltage range of 4.5V to 5.5V, making it suitable for standard digital logic applications.
• Input Logic Levels: It is designed to accept standard TTL input levels, ensuring compatibility with other TTL devices.
• Output Drive Capability: The outputs can drive up to 32 mA, allowing for direct connection to other logic devices or loads.
• Propagation Delay: The typical propagation delay time is around 5 ns at a supply voltage of 5V, which makes it suitable for high-speed applications.

Package Information:

• Package Type: The SN74AHCT86DBR is available in a small, surface-mount SOIC (Small Outline Integrated Circuit) package, which is ideal for space-constrained applications.
• Pin Count: The device has 14 pins, with each pin serving a specific function related to the XOR gates and power supply connections.
• Pin Configuration: The pin configuration includes inputs for each of the four XOR gates, as well as power supply (Vcc) and ground (GND) pins.

Electrical Characteristics:

• Input Voltage Levels: The input high voltage (VIH) is typically 2.0V minimum, while the input low voltage (VIL) is a maximum of 0.8V.
• Output Voltage Levels: The output high voltage (VOH) is typically close to Vcc when the output is high, and the output low voltage (VOL) is close to ground when the output is low.
• Power Consumption: The device has low power consumption, making it suitable for battery-operated devices and energy-efficient applications.

Applications:

The SN74AHCT86DBR is widely used in various digital logic applications, including:

• Arithmetic and logic operations in digital circuits.
• Data processing and control systems.
• Signal processing in communication systems.
• Any application requiring high-speed logic operations with low power consumption.

Conclusion:

The SN74AHCT86DBR from Texas Instruments is a versatile and efficient quad 2-input XOR gate that combines high-speed performance with low power consumption, making it an excellent choice for a wide range of digital logic applications. Its compatibility with TTL levels and robust electrical characteristics further enhance its usability in modern electronic designs.
