Description
NVE’s IL260-Series five-channel 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.

All transmit and receive channels operate at 110 Mbps over the full
temperature and supply voltage range. The symmetric magnetic
coupling barrier provides a typical propagation delay of only 10 ns
and a pulse width distortion of 2 ns, achieving the best specifications
of any isolator. The unique fifth channel can be is used to distribute
isolated clocks or handshake signals to multiple delta-sigma A/D
converters. High channel density makes these devices ideal for
isolating ADCs and DACs, parallel buses and peripheral interfaces.
Typical transient immunity of 50 kV/µs is unsurpassed.
Performance is specified over the temperature range of
−40°C
to
+85°C without derating.
The five-channel devices provide the highest channel density
available. Parts are available in an ultraminiature 16-pin QSOP,
as well as 0.15"and 0.3"-wide SOIC packages.
