ADUM1250ARZ-RL7

ADUM1250ARZ-RL7 is an Analog Devices hot-swappable dual I2C isolator in an 8-lead SOIC package — two bidirectional, open-drain channels that isolate I2C clock and data while tolerating insertion into a live backplane, at bus rates to 1,000 kHz with 30 mA sink capability, from 3.0 V to 5.5 V supplies, with 2,500 Vrms UL isolation and a 560 Vpeak working insulation voltage. Selection advice: the A grade in this code is the −40 to +105 °C version — the 125 °C figure that appears in the datasheet belongs to other temperature grades of the family, so do not qualify this code for 125 °C service; the RL7 suffix is the 1,000-piece tape-and-reel packing. Hot-swap tolerance is what separates the ADuM1250 from plain I2C isolators in rack and telecom backplanes. Analog Devices lists the ADuM1250 as PRODUCTION, with this exact code in the datasheet ordering guide. Parameters verified against Analog Devices documentation.
