FAQs
What is SN65HVD1781D?
The SN65HVD1781D is a low-power, half-duplex RS-485 transceiver designed by Texas Instruments. It is ideal for applications requiring robust communication over long cable lengths in industrial automation, building automation, and automotive systems.
How Does SN65HVD1781D Work?
The SN65HVD1781D works by converting data signals between a differential driver and receiver to enable communication over an RS-485 network. It features high electromagnetic compatibility (EMC) and low electromagnetic interference (EMI) characteristics, making it suitable for harsh industrial environments.
How Many Pins does SN65HVD1781D have and What are the Functions of the Pinout Configuration?
The SN65HVD1781D is housed in an 8-lead SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:
- DE, /RE: Driver enable and receiver enable pins for half-duplex operation.
- A, B: Differential communication pins for RS-485 signals.
- VCC: Positive power supply pin.
- GND: Ground pin.
- Y, Z: Driver output and receiver input pins.
- RO: Receiver output pin.
What are the Pros and Cons of SN65HVD1781D?
Pros:
- Robust Communication: Designed for reliable data transmission over long distances in harsh environments.
- Low Power Consumption: Operates with low power consumption, suitable for battery-powered applications.
- Half-Duplex Operation: Supports half-duplex communication for simplifying network topology.
- Wide Supply Voltage Range: Operates over a wide supply voltage range for flexibility in system design.
