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. Product variants with different channel configurations
and fail-safe default output states are available.

Features
• Data rates up to 40 Mbps
• Wide operating supply voltage 2.7 V - 6.5 V
• Low current consumption (max. 1.6 mA/ch @ 1 Mbps, 3.3 V, 15 pF)
• High CMTI of min. 100 kV/µs
• Propagation delay typ 26 ns with 3 ns channel-to-channel mismatch
• Max 3 ns pulse width distortion @ 3.3 V
