Q & A
- What is the signaling rate of the SN65HVD1050D?
The signaling rate of the SN65HVD1050D is up to 1 megabit per second (Mbps).
- What are the operating temperature ranges for the SN65HVD1050D?
The operating temperature range is from -40°C to 125°C.
- What kind of protection does the SN65HVD1050D offer?
The device offers CAN bus-fault protection from 27 V to 40 V, overvoltage, loss of ground protection, and withstands voltage transients from -200 V to 200 V according to ISO 7637.
- What is the silent mode operation in the SN65HVD1050D?
In silent mode, the driver is switched off while the receiver remains fully functional. This mode is activated by applying a high logic level to the S pin (pin 8).
- What is the dominant time-out function in the SN65HVD1050D?
The dominant time-out function prevents the driver from blocking network communication by disabling the driver if no rising edge is seen on TXD (pin 1) before the time-out constant expires.
- What are the common applications of the SN65HVD1050D?
The device is used in industrial automation, DeviceNet™ data buses, SAE J2284 high-speed CAN bus for automotive applications, SAE J1939 standard data bus interface, ISO 11783 standard data bus interface, and NMEA 2000 standard data bus interface.
- Does the SN65HVD1050D meet any specific standards?
Yes, it meets or exceeds the requirements of the ISO 11898-2 standard.
- What is the purpose of the Vref pin in the SN65HVD1050D?
The Vref pin (pin 5) provides a VCC/2 voltage reference to stabilize the output common mode voltage point.
- How does the SN65HVD1050D handle power cycling?
The device ensures monotonic outputs during power cycling, providing glitch-free CAN bus inputs and outputs.
- What kind of electromagnetic characteristics does the SN65HVD1050D have?
The device features high electromagnetic immunity (EMI) and very low electromagnetic emissions (EME).
