ISO7241CDWR

Texas Instruments Quad-Channel Digital Isolators

Texas Instruments' ISO7241/ISO7242 quad-channel digital isolators are the fastest, most precise digital isolators with the highest magnetic immunity and longest life. The devices have a digital logic input and output buffer separated by TI's capacitive isolation barrier technology thath provides alvanic isolation of up to 4000V. The devices are available in 1Mbps, 25Mbps, and 150Mbps speed grades that can operate from 0Mbps to the rated speed. The devices block high-voltage, isolate grounds, and prevent noise currents from entering the local ground and interfering with or damaging sensitive circuitry.

ISO7241C数字隔离器

Texas Insturments ISO7241C四通道、3/1、25Mbps数字隔离器属于数字隔离器系列，具有多通道配置和输出使能功能。该TI器件具有由TI的二氧化硅 (SiO2) 绝缘隔栅分开的逻辑输入和输出缓冲器。当与隔离电源配合使用时，这些器件可阻止高电压、隔离接地，并防止噪声电流进入本地接地并干扰或损坏敏感电路。ISO7241的三个通道处于同一个方向，另外一个通道处于相反方向。C版本器件具有TTL输入阈值和噪声滤波器（输入端），可防止瞬态脉冲传递到器件的输出端。M版本器件具有CMOS Vcc/2输入阈值，没有输入噪声滤波器或额外的传播延迟。
