Analog Devices Inc. ADuM141D/E四通道数字隔离器
Analog Devices ADuM141D/E符合汽车行业标准的四通道数字隔离器具有最大13ns传播延迟，在5V工作电压时脉冲宽度失真小于3ns。该隔离器具有100kV/µs共模瞬态抑制和最大3.0ns的严格通道匹配。这些数据通道是相互独立的，可提供多种配置选择， 这些数据通道具有150Mbps最大数据速率，可承受3.0kVRMS或3.75kVRMS的电压额定值。ADuM141D/E隔离器可在1.8V至5V电源电压的任一侧工作。这种可在电源电压任一侧工作的能力不仅能够跨越隔离栅实现电压转换功能，还能与低压系统兼容。基于iCoupler®技术，ADuM141D/E隔离器可确保不存在输入逻辑转换时的直流正确性。此外，这些隔离器具有两个不同的故障安全选项。在未提供输入电源或者输入被禁用时，这些故障安全选项可使输出转换为预定的状态。
The ADuM141D/E isolators operate on either side of a supply voltage ranging from 1.8V to 5V. The capability to operate on either side of the supply voltage enables voltage translation functionality across the isolation barrier and compatibility with lower voltage systems.
Based on iCoupler® technology, the ADuM141D/E isolators ensure DC correctness in the absence of input logic transitions. The isolators feature two different fail-safe options. The fail-safe options allow the outputs to transition to a predetermined state when the input power supply is not applied or the inputs are disabled.
