Product details
Overview
ADUM242E1BRIZ from Analog Devices is a 5.0 kVrms quad-channel digital isolator based on iCoupler® technology, providing reinforced galvanic isolation between microcontroller and high-voltage power stage in motor drives. It delivers 150 Mbps data rate, 13 ns max propagation delay at 5 V, and operates across 1.8 V to 5 V supply rails with fail-safe high output configuration.
For engineers reviewing the ADUM242E1BRIZ datasheet, ADUM242E1BRIZ pinout, ADUM242E1BRIZ application, or ADUM242E1BRIZ equivalent, this page provides verified electrical specs, SOIC_W package details, safety certifications (UL 1577, VDE 0884-17), and real-world use cases in industrial SPI isolation and IEC 61010-1 compliant equipment.
Technical Context
The ADUM242E1BRIZ implements monolithic air-core transformer coupling per channel, enabling dc-correct signal transmission without input transitions. Its architecture supports independent bidirectional data paths with tight channel matching (≤3.0 ns codirectional skew) and low jitter (70 ps rms at 5 V).
It features dual-supply operation (VDD1/VDD2 = 1.8–5 V), integrated undervoltage lockout (1.6 V threshold), and failsafe logic-high outputs when input power is absent-critical for safe shutdown in isolated gate driver interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM242D1BRIZ | Fail-safe output state is low (not high); identical timing, isolation, and package | Required where system safety logic demands default-low output during power loss | Select ADUM242D1BRIZ only if hardware-level fail-safe behavior must assert logic low instead of high |
| SI8642ED-B-IS | Capacitive isolation; 5 kVrms, 150 Mbps, but CMTI = 35 kV/µs (vs. 100 kV/µs) | Lower noise immunity limits use in high-dV/dt environments like SiC inverters | Choose SI8642ED-B-IS only for cost-sensitive, lower-noise applications where 35 kV/µs CMTI suffices |
Compared with ADUM242D1BRIZ, ADUM242E1BRIZ provides fail-safe high outputs essential for gate driver disable; compared with SI8642ED-B-IS, it delivers 2.9× higher CMTI critical for robust operation in fast-switching power electronics.

FAQ
What is the maximum guaranteed data rate for ADUM242E1BRIZ?
The ADUM242E1BRIZ has a maximum guaranteed data rate of 150 Mbps across all supply voltages (1.8 V to 5 V). This specification is validated per the datasheet's switching characteristics tables and applies under CL = 15 pF loading with CMOS signal levels. Higher rates may be achievable but are not production-guaranteed.
Does ADUM242E1BRIZ support level translation between different supply voltages?
Yes, ADUM242E1BRIZ supports true bidirectional level translation: VDD1 and VDD2 can operate independently from 1.8 V to 5 V. For example, it can translate 1.8 V logic from an FPGA on side 1 to 3.3 V logic for an MCU on side 2, with full timing compliance and no external components required.
What safety certifications does ADUM242E1BRIZ hold?
ADUM242E1BRIZ is certified to UL 1577 (5000 Vrms), DIN EN IEC 60747-17 (VDE 0884-17), IEC/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 61010-1. These approvals are documented in Tables 12 and 13 of the Rev. E datasheet and apply to the RW-16 SOIC_W package variant.
How does the fail-safe output behavior work on ADUM242E1BRIZ?
When VDD1 is unpowered or input signals are disabled, ADUM242E1BRIZ forces all four outputs (OUTA–OUTD) to logic high. This behavior is intrinsic to the E1 variant and ensures safe shutdown of downstream gate drivers or relays-no external pull-up resistors or supervision circuitry needed.
Is ADUM242E1BRIZ pin compatible with earlier generation isolators?
Yes, ADUM242E1BRIZ is pin compatible with ADUM2402 and ADUM2412 per the datasheet's backward compatibility statement. This allows drop-in replacement in existing designs using those parts, preserving PCB layout and reducing redesign effort for enhanced performance or qualification needs.
