SLLSE89G – SEPTEMBER 2011 – REVISED JANUARY 2015 ISO764xFM Low-Power Quad-Channel Digital Isolators
1 Features 3 Description ISO7640FM and ISO7641FM provide galvanic
isolation up to 6 KVPK for 1 minute per UL and VDE.
These devices are also certified up to 5-KVRMS
Reinforced isolation at a working voltage of 400 VRMS
per end equipment standards EN/UL/CSA 60950-1
and 61010-1. ISO7640F and ISO7641F are quadchannel isolators; ISO7640F has four forward and
ISO7641F has three forward and one reversedirection channels. Suffix F indicates that output
defaults to Low-state in fail-safe conditions (see
Table 4). M-Grade devices are high-speed isolators
capable of 150-Mbps data rate with fast propagation
delays. 1 Signaling Rate: 150 Mbps
Low Power Consumption, Typical ICC per Channel
(3.3-V Supplies):
– ISO7640FM: 2 mA at 25 Mbps
– ISO7641FM: 2.4 mA at 25 Mbps
Low Propagation Delay: 7-ns Typical …
