Overview

The ISL71710SLHM is an active-input digital signal isolator with a CMOS output. It has a similar interface but better performance and higher package density than other optocouplers. The ISL71710SLHM is manufactured with Giant Magnetoresistive (GMR) technology for small size, high speed, and low power. A ceramic/polymer composite barrier provides excellent isolation and an unlimited barrier life. The device is able to interface directly to CMOS/TTL signals at 3.3V or 5V. This versatile component can be used to replace a variety of optocouplers, functioning over a wide range of data rates, edge speeds, and power supply levels. The device output is also compatible with 3.3V and 5V supplies, allowing an interface to controllers without additional level shifting. The ISL71710SLHM is offered in an 8 Ld 5mmx4mm SOIC package and is fully specified across the military ambient temperature range of -55°C to +125°C.
