Description
NVE’s IL700 family of high-speed digital isolators are CMOS
devices manufactured with NVE’s patented* IsoLoop® spintronic
Giant Magnetoresistive (GMR) technology.
A unique ceramic/polymer composite barrier provides excellent
isolation and virtually unlimited barrier life.
The symmetric magnetic coupling barrier provides a typical
propagation delay of only 10 ns and a pulse width distortion as low
as 300 ps (0.3 ns), achieving the best specifications of any isolator.
Typical transient immunity of 50 kV/µs is unsurpassed. The IL710
is ideal for isolating applications such as PROFIBUS, RS-485, and
RS-422.
The IL710 is available in 8-pin MSOP, SOIC, and PDIP packages.
The IL710S is the world’s fastest isolator of its type, with a 150
Mbps typical data rate. Standard and S-Grade parts are specified
over a temperature range of −40°C to +100°C. T-Grade parts are
specified over a temperature range of −40°C to +125°C. The MSOP
V-Series version offers full 2500 VRMS isolation in an ultraminiature
package.
