Product details

Overview

ADUM241E1WBRWZ from Analog Devices is a quad-channel digital isolator using iCoupler® transformer-based isolation, delivering 5.0 kV_rms withstand voltage, 150 Mbps guaranteed data rate, and 13 ns max propagation delay at 5 V operation. It supports 1.8 V to 5 V level translation across the isolation barrier and features fail-safe high output state, making it suitable for SPI isolation in industrial PLC I/O modules.

For engineers reviewing the ADUM241E1WBRWZ datasheet, ADUM241E1WBRWZ pinout, ADUM241E1WBRWZ application, or ADUM241E1WBRWZ equivalent, key selection criteria include reinforced insulation compliance (DIN EN IEC 60747-17), common-mode transient immunity of 100 kV/µs, and pin compatibility with legacy ADuM2400-series devices in SOIC_W packaging.

Technical Context

The ADUM241E1WBRWZ implements four independent unidirectional channels with input-side power (VDD1) and output-side power (VDD2) operating independently from 1.8 V to 5 V. Its iCoupler® technology replaces optocouplers with monolithic air-core transformers, ensuring dc-correct output behavior without input transitions.

It provides fail-safe high output state on power loss or disable, supports tristate outputs via DISABLE1 input, and integrates undervoltage lockout (UVLO) with 1.6 V threshold on both sides. Channel matching is ≤3.0 ns, and pulse width distortion remains ≤3 ns across temperature and supply ranges.

Key Specifications

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
ADUM241D1WBRWZ	Fail-safe output state is low (not high); otherwise identical pinout, specs, and RW-16 package.	Required where default-low enable or reset is needed (e.g., active-low enable for power management ICs).	Select ADUM241D1WBRWZ only when system logic requires active-low fail-safe behavior.
SI8641ED-B-IS	Capacitive isolation; 5.0 kV_rms, 150 Mbps, but 15 ns max propagation delay and no 1.8 V support on secondary side.	Compatible for SPI isolation but not for mixed-voltage level translation involving 1.8 V output-side logic.	Choose SI8641ED-B-IS if cost sensitivity outweighs need for 1.8 V VDD2 operation and sub-13 ns timing.

Compared with ADUM241D1WBRWZ, ADUM241E1WBRWZ provides fail-safe high output essential for driving high-side switches; versus SI8641ED-B-IS, it delivers superior low-voltage interoperability and tighter propagation delay for time-critical control loops.

FAQ

What is the maximum guaranteed data rate for ADUM241E1WBRWZ?

The ADUM241E1WBRWZ guarantees a data rate of 150 Mbps across its full operating temperature range (−40°C to +125°C) and supply voltage range (1.8 V to 5 V). This specification is validated per the datasheet's switching characteristics tables and applies to all four channels simultaneously under CL = 15 pF loading conditions. Higher rates may be achievable but are not production-guaranteed.

Does ADUM241E1WBRWZ support 1.8 V operation on both sides of the isolation barrier?

Yes, ADUM241E1WBRWZ supports 1.8 V to 5 V operation independently on VDD1 (input side) and VDD2 (output side). At 1.8 V, it achieves 15 ns maximum propagation delay and maintains 150 Mbps data rate capability. The input threshold scales as 0.7×VDDx and 0.3×VDDx, ensuring robust logic recognition across the full voltage range.

What safety certifications apply to ADUM241E1WBRWZ?

ADUM241E1WBRWZ holds UL 1577 (5000 V_rms), DIN EN IEC 60747-17 (VDE 0884-17), IEC/CSA 62368-1, IEC/CSA 60601-1 (2 MOPP), and IEC/CSA 61010-1 certifications. Its RW-16 SOIC_W package provides 7.8 mm creepage and clearance, meeting reinforced insulation requirements for medical and industrial end-equipment.

How does the fail-safe high output function in ADUM241E1WBRWZ?

When VDD1 is unpowered, DISABLE1 is asserted high, or input signals are inactive, ADUM241E1WBRWZ forces all four outputs (OUTA–OUTD) to logic high. This behavior is implemented via internal circuitry and does not require external pull-ups. It ensures predictable state during power sequencing, brownout, or communication faults - critical for enabling downstream drivers or latches.

Is ADUM241E1WBRWZ pin-compatible with earlier ADuM2400-series isolators?

Yes, ADUM241E1WBRWZ is pin-compatible with ADuM2400, ADuM2401, and ADuM2402 in the same RW-16 SOIC_W package. This backward compatibility allows drop-in replacement in existing designs without PCB layout changes, preserving established creepage, thermal, and EMI performance while upgrading to enhanced CMTI and fail-safe behavior.
