Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.
Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current,
high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating
Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.

中风发生时，一切都是以秒来计算的。延误治疗可能导致大脑重大损伤。伦敦大学医学院的一位博士Alistair McEwan已经获得行为医学研究所(Action Medical Research)的同意，为急救人员开发一种无线诊断系统来减少时间延误。感谢抗血栓药物，一些病人在病情发作的三个小时之内可以完全恢复。但出血也会导致中风。医生在治疗之前需要确定发病原因，因为不适当的服用抗血栓药物会加重损害。...[详细]
引 言 Controller Area Network(控制器局域网，缩写为CAN)，是为解决汽车电子控制单元间的信息通信而由德国Bosch公司提出的一种总线标准，以其卓越的性能、极高的可靠性和低廉的价格，现在已经在汽车领域获得广泛应用。为了保证汽车CAN总线节点安全、稳定运转，同时为了提高大批量生产的效率，必须在生产过程中对CAN节点产品进行测试，开发基于CAN总线的汽车CAN节点...[详细]
