What are the key features of ADUM3442CRWZ?
- Quad-channel unidirectional (4/0) digital isolator with 2.5 kV rms isolation rating, replacing 4 optocouplers in a single SOIC-16 package
- Up to 25 Mbps per-channel data rate using ADI iCoupler transformer-based technology with low 32 ns propagation delay and no LED current drive required
- Wide 3 V to 5.5 V supply range on both primary and secondary sides enables cross-voltage isolation between 3.3 V logic and 5 V industrial bus interfaces
What is ADUM3442CRWZ used for?
The ADUM3442CRWZ is used in industrial motor drives, PLC digital input modules, and medical equipment signal isolation barriers where four parallel digital channels must cross an isolation boundary at multi-megabit speeds. Its magnetic iCoupler technology eliminates the aging and current-drive limitations of optocouplers, providing consistent 25 Mbps performance over the full -40°C to 105°C operating range. The SOIC-16 package reduces board space compared to four discrete optocoupler packages while simplifying the isolation power budget.

Frequently Asked Questions
What isolation voltage does the ADUM3442CRWZ provide and how does it compare to discrete optocouplers?
The ADUM3442CRWZ is rated at 2.5 kV rms continuous working isolation voltage, meeting IEC 60950 and UL 1577 reinforced isolation requirements for many industrial applications. A single SOIC-16 device replaces 4 discrete optocouplers while offering 10x higher data rate and consistent propagation delay that does not degrade over component lifetime.
At what maximum data rate can the ADUM3442CRWZ transfer digital signals across the isolation barrier?
Each channel supports up to 25 Mbps data rate with a propagation delay of approximately 32 ns. This is significantly faster than standard optocouplers, which typically peak at 1 Mbps to 10 Mbps, making ADUM3442CRWZ suitable for SPI-over-isolation and parallel digital bus applications requiring fast signal transfer.
What channel configuration does the ADUM3442CRWZ offer for system signal direction planning?
The ADUM3442CRWZ provides a 4-channel unidirectional configuration with all 4 channels passing signals from side 1 to side 2. Designers needing bidirectional isolation on the same part should consider ADUM3441 (3/1 split) or ADUM3440 (2/2 split) depending on whether control feedback signals need to cross the barrier in the opposite direction.
How does the ADUM3442CRWZ operating temperature range suit industrial control cabinet designs?
Rated from -40°C to 105°C, the ADUM3442CRWZ covers the full industrial operating range required for motor drive control boards and PLC backplane modules. The 105°C upper limit provides 20°C headroom above the 85°C ambient temperature typically specified for cabinet-mounted electronics without forced air cooling.
