Product details

Overview

ADUM242E0BRIZ from Analog Devices is a quad-channel digital isolator based on iCoupler® technology, providing 5.0 kV_rms reinforced insulation for high-noise industrial and medical systems. It delivers 150 Mbps guaranteed 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. It is used in isolated SPI interfaces for motor drives and PLC I/O modules.

For engineers reviewing the ADUM242E0BRIZ datasheet, ADUM242E0BRIZ pinout, ADUM242E0BRIZ application, or ADUM242E0BRIZ equivalent, key selection criteria include its 5.0 kV_rms isolation rating, 100 kV/µs common-mode transient immunity, SOIC_W-16 package with 7.8 mm creepage, and compatibility with 1.8 V–5 V level translation across the barrier.

Technical Context

The ADUM242E0BRIZ implements four independent unidirectional channels using monolithic air-core transformer coupling, ensuring dc-correct output states without input transitions. Its architecture supports asymmetric voltage operation (e.g., 1.8 V on side 1, 5 V on side 2) and includes integrated undervoltage lockout (UVLO) with 1.6 V threshold on both sides.

It features fail-safe high output behavior when input power is absent or disabled, and provides tight channel matching (≤3.0 ns codirectional skew) and low jitter (70 ps rms at 5 V). The device meets DIN EN IEC 60747-17 (VDE 0884-17) for reinforced insulation at 849 V_peak.

INA, INB, INC, IND	Digital input signals	CMOS-compatible inputs referenced to VDD1; VIH = 0.7×VDD1, VIL = 0.3×VDD1
VDD2	Secondary-side power supply	Supplies logic side 2 (outputs A–D); independent 1.8 V–5 V rail; UVLO active below 1.5 V
GND2	Secondary-side ground reference	Return path for VDD2; galvanically isolated from GND1; defines output logic levels
OUTA, OUTB, OUTC, OUTD	Digital output signals	CMOS outputs referenced to VDD2; VOH ≥ VDD2 − 0.4 V @ 4 mA, VOL ≤ 0.4 V @ 4 mA
DISABLE1	Input-side disable control	Pull-down enabled; asserts when tied to VDD1, forcing all inputs to high-impedance state
VE2	Output-enable control	Pull-up enabled; asserts when grounded, placing all outputs in high-impedance state

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad digital isolator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADUM242E1BRIZ	Pin-compatible but with fail-safe low output state instead of high	Suitable for active-low enable paths (e.g., reset lines), not direct replacement where high-default is required	Select ADUM242E1BRIZ only when system logic requires low-state default on power loss
SI8642ED-B-IS	Capacitive isolation; 5.0 kV_rms; 150 Mbps; SOIC-16; failsafe high; but 60 kV/µs CMTI (vs. 100 kV/µs)	Lower noise immunity limits use in high-di/dt motor drives; identical pinout enables drop-in evaluation	Choose SI8642ED-B-IS only if CMTI >80 kV/µs is not required and cost sensitivity outweighs noise robustness

Compared with ADUM242E1BRIZ, ADUM242E0BRIZ ensures fail-safe high outputs critical for enabling circuits, while SI8642ED-B-IS offers lower CMTI and different isolation physics-making ADUM242E0BRIZ preferred for high-noise industrial motion control and medical isolation where reliability under fast transients is mandatory.

FAQ

What is the maximum guaranteed data rate for ADUM242E0BRIZ?

The ADUM242E0BRIZ guarantees a maximum data rate of 150 Mbps across all operating conditions (−40°C to +125°C, 1.8 V–5 V supplies). This is validated per datasheet Table 1–Table 4 switching specifications and applies to all four channels simultaneously with pulse width distortion maintained below 3 ns.

Does ADUM242E0BRIZ support level translation between different supply voltages?

Yes, ADUM242E0BRIZ supports true bidirectional level translation: VDD1 can operate from 1.8 V to 5 V independently of VDD2, which also ranges from 1.8 V to 5 V. This allows direct interfacing between, for example, a 1.8 V microcontroller and a 5 V peripheral without external level-shifting circuitry.

What safety certifications does ADUM242E0BRIZ hold?

ADUM242E0BRIZ is certified to UL 1577 (5000 V_rms), IEC/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), IEC/CSA 61010-1, CQC GB4943.1, and DIN EN IEC 60747-17 (VDE 0884-17) with VIORM = 849 V_peak, confirming reinforced insulation for medical and industrial safety-critical designs.

What is the fail-safe behavior of ADUM242E0BRIZ on power loss?

ADUM242E0BRIZ is configured as an E0 variant, meaning its outputs default to logic high when VDD1 is unpowered or when DISABLE1 is asserted. This fail-safe high state prevents undefined logic levels in safety-critical paths such as gate driver enables or relay controls during brownout conditions.

How does ADUM242E0BRIZ compare to optocouplers in terms of propagation delay stability?

ADUM242E0BRIZ achieves 13 ns maximum propagation delay at 5 V with ±1.5 ps/°C temperature drift and ≤3.0 ns channel matching - significantly tighter and more stable than optocouplers, which typically exhibit >100 ns delays with >10 ns unit-to-unit variation and strong temperature dependence due to LED aging and CTR degradation.
