The ISOM8110-EP device is a single-channel optocoupler-emulator with LED-emulator input and transistor output. The device is footprint compatible and pin-to-pin upgrades for many traditional optocouplers, allowing enhancement to existing systems with no PCB redesign.

ISOM8110-EP opto-emulator offers 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.

ISOM8110-EP is offered in a small SOIC-4 package with 2.54mm pin pitch, supporting a 3750VRMS isolation rating. The high performance and reliability of ISOM8110-EP enables the device to be used in power supply feedback design, avionics, defense, and more.

Evaluation board

ISOM-EVM — Universal opto-emulator evaluation module

The ISOM-EVM supports evaluation of TI opto-emulators in 5-pin DFF, 4-pin DFG, 4-pin DFH and 4-pin DFS SOIC packages. The evaluation module (EVM) can be reconfigured for evaluation of different opto-emulators, different input signal or other applications by changing the EVM configuration and (...)
