Description
The ISOM811x-Q1 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-Q1 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-Q1 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]-Q1) and bidirectional DC (ISOM811[5-8]-Q1) input options. The high performance and reliability of ISOM811x-Q1 enables these devices to be used in power supply feedback design, motor drives, I/O modules in industrial controllers, factory automation applications, and more.
