ISL71610M

Radiation Tolerant Passive-Input Digital Isolator

Product Status: Mass Production

OVERVIEW

The ISL71610M is a passive-input digital signal isolator with a CMOS output. It has a similar interface but better performance and higher package density than other optocouplers.

The ISL71610M 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. A series external resistor sets the input coil current and a capacitor in parallel with the current-limiting resistor provides improved dynamic performance. 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 compatible with 3.3V and 5V supplies, allowing an interface to controllers without additional level shifting. With the coil energized with a minimum of ±8mA (bidirectional current) the ISL71610M is suitable for single ended and differential drive applications.

The ISL71610M 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.
