Texas Instruments ISO7342FCDW

The ISO734x family of devices provides galvanic isolation up to 3000 VRMS for 1 minute per UL 1577 and 4242 VPK per VDE V 0884-10. These devices have four isolated channels comprised of logic input and output buffers separated by a silicon dioxide (SiO2) insulation barrier.

The ISO7340x device has four channels in forward direction, the ISO7341x device has three forward and one reverse-direction channels, and the ISO7342x device has two forward and two reverse-direction channels. In case of input power or signal loss, the default output is for devices with suffix and for devices without suffix . See the section for further details.

Used in conjunction with isolated power supplies, these devices help prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. The ISO734x device has integrated noise filter for harsh industrial environment where short noise pulses may be present at the device input pins. The ISO734x device has TTL input thresholds and operates from 3-V to 5.5-V supply levels. Through innovative chip design and layout techniques, electromagnetic compatibility of the ISO734x family of devices has been significantly enhanced to enable system-level ESD, EFT, surge, and emissions compliance.

For all available packages, see the orderable addendum at the end of the datasheet.

设备的iso734x家庭提供电隔离到3000 Vrms每UL 1577和4242每1分钟0884-10 VPK VDE V。这些设备有四个隔离通道,由逻辑输入和输出缓冲区组成,由二氧化硅(二氧化硅)绝缘屏障隔开。
与单独的电源一起使用,这些设备有助于防止数据总线或其他电路的噪声电流进入本地地面,干扰或损坏敏感电路。的iso734x装置集成了噪声滤波器用于苛刻的工业环境中的短脉冲噪声可以在装置的输入引脚。的iso734x装置具有TTL输入阈值和经营从3 - V至5.5 V的供应水平。通过创新的芯片设计和布局技术,对设备的电磁兼容性iso734x家庭得到显著增强,使系统级ESD、EFT,浪涌,和排放标准。
