The SN74LVC861ADW is a high-performance, 10-bit bus transceiver designed by Texas Instruments, a global leader in semiconductor technology. This integrated circuit is part of the LVC family, which stands for Low-Voltage CMOS, indicating its compatibility with low-voltage operation and its CMOS technology design.

Key Features

• Wide Operating Voltage Range: The SN74LVC861ADW operates at a voltage range of 2.7V to 3.6V, making it suitable for interfacing with both 3.3V and 2.5V logic levels.
• High-Drive Outputs: The outputs can drive up to 24 mA, providing good signal strength for driving heavy loads or for use in bus-oriented systems.
• IOFF Support: The IOFF circuitry ensures that no damaging current will flow through the device when it is powered down. This feature is crucial for power-saving modes.
• Bus Hold Data Inputs: The bus hold feature retains the inputs’ last known state, preventing them from floating when no driving signal is present, which enhances the stability of the system.
• Flow-Through Architecture: The pinout of the SN74LVC861ADW is designed for easy PCB routing, minimizing signal skew and simplifying board layout.

Applications

The SN74LVC861ADW is typically used in applications that require bidirectional data flow and buffering. This includes data exchange between different voltage domains in systems such as:

• Microprocessor or Microcontroller based systems
• Data communication equipment
• Computers and peripherals
• Networking switches and routers

Package and Quality

The device comes in a 24-pin wide-body SOIC package (DW suffix), which is suitable for surface-mount technology (SMT). It offers a balanced compromise between space-saving and ease of handling during manufacturing. Texas Instruments is known for its commitment to quality, and the SN74LVC861ADW is no exception, ensuring reliable performance and longevity in a wide range of environments and applications.
