Description
IN1
OUT1
IN2
OUT2
IN3
OUT3
A unique ceramic/polymer composite barrier provides excellent isolation
and virtually unlimited barrier life.
IN4
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.

IL717
NVE’s IL715, IL716, and IL717 four-channel high-speed digital isolators
are CMOS devices manufactured with NVE’s patented* IsoLoop®
spintronic Giant Magnetoresistive (GMR) technology.
Typical transient immunity of 50 kV/µs is unsurpassed. High channel
density makes these devices ideal for isolating ADCs and DACs, parallel
buses and peripheral interfaces.
The IL715, IL716, and IL717 are available in 16-pin 0.3" and 0.15" SOIC,
and ultraminiature QSOP packages.
Performance is specified over a temperature range of −40°C to +100°C.
“T” and “V” Series parts have a maximum operating temperature of 125°C.
V-Series versions have an extremely high isolation voltage of 6 kVRMS.
IsoLoop is a registered trademark of NVE Corporation.
