The ISOM8110 device is capable of being pin-compatible and drop-in replaceable with many opto-coupler devices with transistor outputs. Opto-emulators offer significant reliability and performance advantages compared to traditional opto-couplers, including tighter current transfer ratio (CTR), low input current, and wider temperature ranges.
The ISOM8110 Opto-Emulator replicates the characteristics of traditional opto-couplers without the drawbacks of aging and thermal drift by using a input-diode emulator and output stage separated by a silicon oxide (SiO2) insulation barrier. When used with isolated power supplies, these devices block high voltages, isolate grounds, and prevent noise currents from interfering with or damaging sensitive circuitry.
