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 pitches, supporting 3750VRMS and 5000VRMS isolation ratings with 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 — 通用光學模擬器評估模組

ISOM-EVM 支援評估採用 5 針腳 DFF、4 針腳 DFG、4 針腳 DFH 和 4 針腳 DFS SOIC 封裝的 TI 光電模擬器。透過變更 EVM 配置和元件值即可重新配置評估模組 (EVM)，以評估不同光電模擬器、不同輸入訊號或其他應用。EVM 在電路板上並未安裝光學模擬器 IC，讓使用者可安裝自己選擇的相容 IC。使用者可將電路板分成三個獨立單元，以個別測試印刷電路板。
