The ISOM811x devices are single-channel optocoupler-emulators with LED-emulator input and transistor output. The devices are footprint compatible and pin-to-pin upgrades for many traditional optocouplers, allowing enhancement to existing systems with no PCB redesign.

ISOM811x opto-emulators offer significant reliability and performance advantages compared to optocouplers, including high bandwidth, low turn-off delay, low power consumption, wider temperature ranges, flat CTR, and tight process controls resulting in small part-to-part skew. Since there is no aging effect or temperature variation to compensate for, the emulated LED input stage consumes less power than optocouplers.

ISOM811x devices are offered in small SOIC-4 packages with 2.54mm and 1.27mm pin pitchs, supporting a 3.75kVRMS isolation rating and DC (ISOM811[0-3]) and bidirectional DC (ISOM811[5-8]) input options. The high performance and reliability of ISOM811x enables these devices to be used in power supply feedback design, motor drives, I/O modules in industrial controllers, factory automation applications, and more.

ISOM-EVM — 通用光耦仿真器评估模块

ISOM-EVM 支持评估采用 5 引脚 DFF、4 引脚 DFG、4 引脚 DFH 和 4 引脚 DFS SOIC 封装的 TI 光耦仿真器。通过更改 EVM 配置和元件值,可以重新配置该评估模块 (EVM),以对不同的光耦仿真器、不同的输入信号或其他应用进行评估。该 EVM 没有在电路板上安装光耦仿真器 IC,允许用户安装自己选择的兼容 IC。用户可以将电路板分为三个单独的单元来单独测试印刷电路板。
