ADUM342E1BRWZ-RL

Overview

The ADUM342E1BRWZ-RL is a quad-channel digital isolator from the Analog Devices ADuM342E series, utilizing iCoupler magnetic coupling technology. It features four independent data channels with unidirectional polarity and supports data rates up to 150 Mbps. The device operates on supply voltages ranging from 2.25 V to 5.5 V and provides an insulation voltage of 3000 Vrms. It is housed in a QSOP-16 surface-mount package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates four independent bidirectional or unidirectional data channels using monolithic air-core transformer technology for robust signal isolation.
• Provides high common-mode transient immunity to suppress noise interference in electrically noisy industrial environments.
• Supports flexible logic levels with wide operating supply voltage ranges compatible with various low-voltage systems.

Applications

• Isolating serial peripheral interface (SPI) communication lines
• Separating RS-485 and Controller Area Network (CAN FD) bus interfaces
• Isolating PWM controller signals in power management circuits

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct channel directionality and insulation ratings. Confirm package type compatibility during integration. Check current availability status as distribution may be limited. Ensure environmental compliance requirements match project specifications before finalizing procurement orders.

Selection Notes

Select this component when requiring four isolated channels with high-speed data transmission capabilities. Consider the unidirectional channel configuration for specific signal flow requirements. Evaluate thermal performance within the specified operating temperature range. Compare insulation voltage ratings against system safety standards to ensure adequate protection margins.

Part Context

This part belongs to the ADuM342E family of quad-channel digital isolators designed for applications demanding high reliability and noise immunity. The series integrates CMOS technology with magnetic coupling to replace traditional optocouplers. These devices offer superior performance characteristics including lower propagation delay and tighter channel matching compared to legacy isolation solutions.

Replacement Considerations

Cross-reference with ADUM342E0BRWZ variants for bidirectional channel requirements. Verify pinout compatibility with existing PCB layouts when substituting similar quad-channel isolators. Ensure equivalent insulation voltage ratings are maintained for safety compliance.
