Description
NVE’s IL700 family of high-speed digital isolators are CMOS devices
manufactured with NVE’s patented* IsoLoop
®
spintronic Giant
Magnetoresistive (GMR) technology. The IL711S and IL712S are the
world’s fastest two-channel isolators, with a 150 Mbps typical data rate for
both channels.
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 IL711 has two transmit channels; the IL712 and IL721 have one
transmit and one receive channel. The IL712 and IL721 operate full
duplex, making them ideal for many fieldbus applications, including
PROFIBUS, DeviceNet, and CAN. The IL721 has channels reversed to
better suit certain board layouts.
Standard and S-Grade parts are specified over a temperature range of
−40°C
to +100°C; T-Grade parts have a maximum operating temperature
of +125°C.
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.
