    SN75179BDR Typical application Circuitry


    The SN75179BDR is a differential driver and receiver pair designed for balanced transmission lines, conforming to TIA/EIA-485 (RS-485) and ITU-T V.11 (X.27) standards. It's primarily used in applications requiring reliable data transmission over long distances or in noisy settings, such as industrial control systems, networking infrastructure, and data communication systems.

    Application Scenario: RS-485 Communication Network

    In this setup, SN75179BDR is employed to establish a dependable RS-485 communication link between devices within an industrial control system.

    Circuit Connection Details

    1. Connecting Differential Driver Outputs

    - The driver outputs (D1 and D2, Pins 6 and 7) of SN75179BDR are connected to the RS-485 network's differential data lines (A and B).

    - Attention to the use of twisted pair cables is necessary to reduce noise and maintain signal integrity.

    2. Attaching Driver Input

    - The driver input (DI, Pin 5) of SN75179BDR is linked to the transmitting device's data output.

    - Ensuring proper logic levels and impedance matching is essential for efficient data transmission.

    3. Linking Receiver Output

    - The receiver output (RO, Pin 2) of SN75179BDR is connected to the receiving device's data input.

    - Implementing filtering and shielding strategies is important to mitigate the impact of noise on received data.

    4. Establishing Receiver Inputs

    - The receiver inputs (R1 and R2, Pins 3 and 4) of SN75179BDR are attached to the RS-485 network's differential data lines (A and B).

    - Utilizing twisted pair cables for these connections is crucial for minimizing electromagnetic interference.

    5. Power Supply Integration

    - VCC (Pin 8) is connected to a +5V power supply, and GND (Pin 1) is linked to the system ground.

    - Deploying decoupling capacitors close to the power pins is important to ensure noise filtration and a stable power supply for SN75179BDR.

    Design Considerations

    Incorporating SN75179BDR into a circuit involves several important considerations:

    1. Bus Termination

    - Proper termination at the RS-485 bus ends is necessary to match the cable's characteristic impedance and minimize signal reflections.

    2. Managing Common-Mode Voltage

    - The common-mode voltage of the bus should be kept within the acceptable range of SN75179BDR to prevent potential damage and ensure consistent operation.

    3. Ensuring Signal Integrity

    - Employing twisted pair cables for differential signals and maintaining appropriate cable shielding is vital to protect against external noise sources.

    4. Implementing Isolation

    - In environments with significant electrical noise, isolating SN75179BDR from the rest of the circuit may be advisable to avoid noise coupling.

    5. Stabilizing Power Supply

    - Providing SN75179BDR with a clean and stable power supply, complemented by proper filtering and decoupling, is essential to manage transient loads and suppress noise effectively.

    By meticulously considering these aspects and leveraging the operational characteristics of SN75179BDR, engineers can effectively utilize this component in RS-485 communication networks, ensuring robust and reliable data transmission in demanding industrial settings.
