Description
NVE's family of high-speed digital isolators are CMOS
devices created by integrating active circuitry and our GMR-
based and patented* IsoLoop® technology. The IL260 and
IL261 are five channel versions of the world's fastest digital
isolator with a 110 Mbps data rate. This device provides the
designer with the most compact isolated logic devices yet
available. 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 device.
Typical transient immunity of 30 kV/µs is unsurpassed. High
channel density make them ideally suited to isolating multiple
ADCs and DACs, parallel buses and peripheral interfaces.
Performance is specified over the temperature range of -40°C
to +85°C without any derating. .
Isoloop® is a registered trademark of NVE Corporation.
*U.S. Patent number 5,831,426; 6,300,617 and others.

Notes:
(Apply to both 3.3 V and 5 V specifications.)
1. Absolute Maximum ambient operating temperature means the device will not be damaged if operated under these conditions. It
does not guarantee performance.
2. PWD is defined as | t
PHL
– t
PLH
|. %PWD is equal to the PWD divided by the pulse width.
3. t
PSK
is equal to the magnitude of the worst case difference in t
PHL
and/or t
PLH
that will be seen between units at 25°C.
4. CM
H
is the maximum common mode voltage slew rate that can be sustained while maintaining V
O
> 0.8 V
DD
. CM
L
is the
maximum common mode input voltage that can be sustained while maintaining V
O
< 0.8 V. The common mode voltage slew
rates apply to both rising and falling common mode voltage edges.
5. Device is considered a two terminal device: pins 1-8 shorted and pins 9-16 shorted.
6. Dynamic power consumption numbers are calculated per channel and are supplied by the channel’s input side power supply.
