ISL71710M

Radiation Tolerant Active-Input High Speed Digital Isolator

Product Status: Mass Production

OVERVIEW

The ISL71710M is an active input digital signal isolator with CMOS output, using Giant Magnetoresistive (GMR) technology for small size, high speed, and low power. The ISL71710M is the fastest isolator of its type, with a 150Mbps typical data rate. The symmetric magnetic coupling barrier provides a typical propagation delay of only 10ns and a pulse-width distortion as low as 0.3ns, achieving the best specifications of any isolator.

The ISL71710M has unsurpassed common-mode transient immunity of 50kV/µs. It is ideal for isolating applications such as PROFIBUS, RS-485, and RS-422.

The ISL71710M is offered in an 8 Ld 5mm x 4mm SOIC package and is fully specified across the military ambient temperature range of -55°C to +125°C.
