ADUM140E0BRWZ

Overview

The ADUM140E0BRWZ is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 3750 Vrms isolation voltage with a data rate of 150 Mbps and common-mode transient immunity of 75 kV/µs. The device operates on a single supply voltage ranging from 1.7 V to 5.5 V, drawing 12 mA typical supply current per channel. Propagation delay is 13 ns maximum, with rise and fall times of 2.5 ns. It supports unidirectional signal transmission in a 16-SOIC package rated for -40°C to +125°C.

Feature Summary

• Integrates four independent channels using monolithic air core transformer technology for robust signal isolation.
• Provides high common-mode transient immunity to maintain signal integrity in noisy environments.
• Supports wide operating supply voltages compatible with various logic families.

Applications

• General-purpose digital isolation for industrial communication buses
• Signal isolation in medical equipment requiring reinforced insulation
• Isolation barriers in power monitoring and control systems

Procurement Notes

Verify the specific suffix 'WZ' indicates the wider SOIC-16 package (7.50mm width) compared to standard variants. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for obsolescence notices or limited availability as distribution status may vary by region.

Selection Notes

Select this component when four isolated channels are required within a single package. Ensure the 3750 Vrms isolation rating meets system safety standards. Verify that the 150 Mbps speed is sufficient for the target application protocol. Consider the 16-SOIC footprint constraints during PCB layout design.

Part Context

This part belongs to the ADUM140E series of iCoupler digital isolators. It shares architectural similarities with the ADUM140E1BRWZ but differs in isolation voltage ratings and packaging options. The series leverages CMOS technology to replace traditional optocouplers in high-speed applications.

Replacement Considerations

Public confirmed substitute: ADUM140E1BRWZ. Note that substitution requires verification of isolation voltage differences and package width compatibility.
