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 IL711S and IL712S are the world’s fastest two-channel isolators, with
a 150 Mbps typical data rate for both channels. Standard and S-Grade parts
are specified over a temperature range of
−40°C
to +100°C; “T” and “VE”
Grade parts have a maximum operating temperature of 125°C. V-Series
versions offer extremely high isolation voltages of 6 kV
RMS
for wide-body
packages and 2.5 kV
RMS
for MSOPs.
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 IL711 has two transmit channels; the IL712 and IL721 have one
transmit and one receive channel. The IL721 has channels reversed to
better suit certain board layouts.
The IL711 and IL712 are available in 8-pin MSOP, SOIC, and PDIP
packages. The IL711 and IL721 are also available in NVE’s unique
JEDEC-compliant 16 pin package with True 8 mm creepage under
IEC 60601.
IsoLoop is a registered trademark of NVE Corporation.
