ISOFACE™ Digital Isolator 4DIRx4xxH family Robust Digital Isolators with precise timing and low power consumption Description The ISOFACE™ 4DIRx4xxH quad-channel digital isolator family supports data rates up to 40 Mbps and ensures robust data communication over a wide ambient operating temperature range (-40°C to +125°C) and across production spread. Infineon’s robust Coreless Transformer (CT) technology provides high immunity against system noise (CMTI of min. 100 kV/µs) and withstands up to 5700 Vrms isolation voltage (VISO). Four data channels in a PG-DSO-16 wide-body 300 mil package allow simplified and high power density designs and improve system efficiency with low power consumption.
