Isolation Applications

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 IL711 and IL712 are two channel versions of the world's

fastest digital isolator with a 110 Mbaud data rate. These devices offer true

isolated logic integration in a level not previously 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 IL711 has two transmit

channels; the IL712 has one transmit channel and one receive channel. The

IL712 operates in full duplex mode making it ideal for many field bus

applications. PROFIBUS and RS485 configurations are achieved by

combining the IL711/12 and the IL710, which together meet the overall

propagation delay specification.

The IL711 and IL712 are available in 8-pin PDIP and 8-pin SOIC packages

and performance is specified over the temperature range of -40°C to

+100°C without any derating.
