Q & A
- What is the primary function of the SN65HVD230QD?
The SN65HVD230QD is a 3.3-V CAN transceiver designed to interface a single-ended CAN controller with a differential CAN bus. - What is the operating temperature range of the SN65HVD230QD?
The operating temperature range is -40°C to 125°C. - What is the maximum signaling rate supported by the SN65HVD230QD?
The maximum signaling rate is up to 1 Mbps. - What kind of ESD protection does the SN65HVD230QD offer?
The SN65HVD230QD offers ESD protection that exceeds 2000 V per MIL-STD-883, Method 3015, and exceeds 200 V using the Machine Model (C = 200 pF, R = 0). - What are the different modes of operation for the SN65HVD230QD?
The SN65HVD230QD supports high-speed, slope control, and low-power standby modes. - How does the low-power standby mode work on the SN65HVD230QD?
In the low-power standby mode, the driver is switched off, and the receiver remains active if a high logic level is applied to RS (pin 8). The DSP controller reverses this mode when a dominant state occurs on the bus. - Is the SN65HVD230QD compatible with automotive applications?
Yes, the SN65HVD230QD is qualified for automotive applications. - What is the typical current consumption in standby mode for the SN65HVD230QD?
The typical current consumption in standby mode is 370 µA. - Does the SN65HVD230QD have thermal shutdown protection?
Yes, the SN65HVD230QD features thermal shutdown protection. - Is the SN65HVD230QD still in production?
No, the SN65HVD230QD is obsolete and no longer in production.
