    FAQs

    What is SN65HVD32DR?

    The SN65HVD32DR is a 3.3V, half-duplex RS-485 transceiver designed by Texas Instruments. It is commonly used in industrial control systems, building automation, and other applications requiring robust communication over long distances.

    How Does SN65HVD32DR Work?

    The SN65HVD32DR operates as a half-duplex transceiver for RS-485 communication. It enables bidirectional data transmission over a differential pair of wires, allowing communication between multiple nodes in a network. The transceiver features enhanced ESD protection and low power consumption for reliable and efficient data transmission.

    How Many Pins does SN65HVD32DR have and What are the Functions of the Pinout Configuration?

    The SN65HVD32DR is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

    • A, B: Differential communication pins for RS-485 data transmission.
    • GND: Ground pin.
    • RE, DE: Receiver output enable and driver output enable pins for direction control.
    • VCC: Power supply input pin.
    • -9, -27: Undervoltage lockout pins for enhanced system reliability.

    What are the Pros and Cons of SN65HVD32DR?

    Pros:

    • Robust Communication: Designed for reliable data transmission over long distances in noisy environments.
    • ESD Protection: Features enhanced ESD protection to safeguard against electrostatic discharge events.
