Q & A
- What is the primary function of the SN65HVD1050DG4? The SN65HVD1050DG4 is a CAN bus transceiver that provides differential transmit and receive capabilities to a CAN controller.
- What is the operating temperature range of the SN65HVD1050DG4? The device operates from -40°C to 125°C.
- What is the maximum data rate supported by the SN65HVD1050DG4? The device supports data rates up to 1 megabit per second (Mbps).
- What kind of protection does the SN65HVD1050DG4 offer against bus faults? The device offers CAN bus fault protection from -27 V to 40 V and voltage transients from -200 V to 200 V.
- How does the dominant time-out function work in the SN65HVD1050DG4? The dominant time-out function prevents the driver from blocking network communication by disabling it if no rising edge is seen on TXD before the time-out constant expires.
- What is the purpose of the mode control pin (S) in the SN65HVD1050DG4? The mode control pin (S) allows the device to enter a listen-only silent mode where the driver is switched off while the receiver remains functional.
