Description
5OUT
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 Mbaud data rate. These
devices provide the designer with the most compact isolated logic
devices yet available. All transmit and receive channels operate at 110
Mbd 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. The IL260 has five transmit channels, while the
IL261 has four transmit channels and one receive channel. Their 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.
