Product details
Overview
MAX14932CASE+ from Analog Devices is a 4-channel, unidirectional digital isolator with 2.75kVRMS galvanic isolation, 150Mbps maximum data rate, and independent 1.71V–5.5V dual-supply operation across isolated domains. It features 6.67ns minimum pulse width, 5.1ns typical propagation delay (tPLH), and operates from –40°C to +125°C - designed for high-speed industrial SPI, RS-485, and battery management interfaces.
For engineers reviewing the MAX14932CASE+ datasheet, MAX14932CASE+ pinout, MAX14932CASE+ application, or MAX14932CASE+ equivalent, this device delivers verified 150Mbps performance with <1ps pulse-width distortion at 5V, robust 25kV/µs CMTI, and VDE-certified basic insulation - critical for functional safety in motor drives and medical isolation barriers.
Technical Context
The MAX14932CASE+ implements capacitive isolation with proprietary silicon-dioxide dielectric barrier, supporting full-duplex unidirectional channel configuration (2 channels A→B, 2 channels B→A). Its architecture enables simultaneous high-speed signal transfer across isolated power domains without ground-loop coupling or level-shifting circuitry.
It integrates enable-controlled three-state outputs (tEN = 5.1ns typ, tTRI = 2.7ns typ) and supports fail-safe default-low output behavior when inputs are unpowered. All four channels are production-tested at +125°C and qualified per UL1577, VDE 0884-11, and IEC 61000-4-5 ±10kV surge standards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISO7841DWR | 4-channel, 100Mbps max, 5000VRMS isolation, 2.5V–5.5V supplies | Higher isolation rating but lower speed; requires external level shifters below 2.5V | Preferred where >5kVRMS is mandated (e.g., grid-tied inverters), not for 150Mbps SPI links |
| ADUM4402ARWZ | 4-channel, 1Mbps max, 5000VRMS, 3.0V–5.5V only | Orders-of-magnitude slower; no 1.8V support or high-CMTI design | Only suitable for low-speed control signaling (e.g., enable/status lines), not data-intensive interfaces |
Compared with ISO7841DWR and ADUM4402ARWZ, MAX14932CASE+ uniquely balances 150Mbps speed, 2.75kVRMS isolation, 1.71V operation, and 25kV/µs CMTI - making it the sole option for compact, high-bandwidth, safety-certified isolation in space-constrained industrial controllers.

FAQ
What is the maximum data rate supported by MAX14932CASE+?
MAX14932CASE+ supports a maximum data rate of 150Mbps, verified across all supply voltages (1.71V–5.5V) and temperatures (–40°C to +125°C). This is confirmed in the Dynamic Electrical Characteristics table for MAX1493_B/E variants, with minimum pulse width of 6.67ns and propagation delay as low as 5.1ns (tPLH, typ @ 5V).
Does MAX14932CASE+ support 1.8V logic on both sides?
Yes, MAX14932CASE+ fully supports 1.71V–5.5V operation on both VDDA and VDDB supplies. At 1.8V, it achieves 150Mbps with 8.1ns tPLH (max), 160ps peak eye jitter, and maintains 25kV/µs CMTI - enabling direct interface with low-voltage FPGAs and microcontrollers without level translation.
What safety certifications does MAX14932CASE+ hold?
MAX14932CASE+ is certified to UL1577 (3750VRMS), cUL (CSA 5A), VDE 0884-11:2017 (Basic Insulation), TUV, and IEC 61000-4-5 (±10kV surge). It meets 443VRMS working voltage (VIOWM), 630VPK repetitive peak (VIORM), and 4600VPK transient isolation (VIOTM) per IEC 60747-5-5.
How does the enable functionality work on MAX14932CASE+?
MAX14932CASE+ features two independent enable pins: ENA controls OUTA1/OUTA2 (B→A direction), and ENB controls OUTB1/OUTB2 (A→B direction). When asserted high, outputs drive CMOS levels; when low, they enter high-impedance state within 2.7ns (tTRI, typ @ 5V), supporting shared-bus architectures.
What is the default output state of MAX14932CASE+ when inputs are unpowered?
MAX14932CASE+ is configured as default-low: when INA_/INB_ inputs are unpowered (floating or at 0V), the corresponding OUTA_/OUTB_ outputs settle to logic low. This fail-safe behavior is fixed per device variant and documented in the Product Selector Guide for MAX14932 suffix "C" (default-low).
