Replacement verdict
Not a drop-in replacement
The ADM3050EBRIZ and ADM3067ETRZ-EP-R7 are not functionally interchangeable. The ADM3050EBRIZ is an isolated CAN transceiver, while the ADM3067ETRZ-EP-R7 is a non-isolated RS-485/RS-422 transceiver, so they serve fundamentally different interface and isolation roles. Substitution is not recommended without a full system-level redesign.

Key electrical and mechanical differences between the two devices
| Parameter | ADM3050EBRIZ | ADM3067ETRZ-EP-R7 | Why it matters |
|---|---|---|---|
| Function / Protocol | Isolated CAN transceiver (CAN FD capable) | Isolated RS-485/RS-422 transceiver | These devices serve different bus protocols (CAN vs RS-485), so they are not functionally interchangeable in a given network. |
| Data Rate | Up to 12 Mbps (CAN FD) | Up to 500 kbps | Maximum signaling speed determines whether the part meets the bandwidth requirements of the application. |
| Isolation Rating | 5 kV rms (galvanic isolation) | 5 kV rms (galvanic isolation) | Isolation voltage rating is critical for safety and ground-loop immunity in industrial and medical systems. |
| Supply Voltage | 5 V (single supply) | 3.0 V to 5.5 V | Supply range affects compatibility with the host logic and power rail design. |
| Duplex / Channel Configuration | Half-duplex CAN (single channel) | Half-duplex RS-485 (single channel) | The bus topology and driver/receiver arrangement must match the network architecture. |
| Operating Temperature Range | -40 °C to +125 °C | -55 °C to +125 °C (EP grade) | Extended temperature range matters for harsh-environment and enhanced-product (EP) applications. |
| Package | 20-lead SOIC (wide body) | 14-lead SOIC | Footprint and pin count must match the PCB layout for a drop-in replacement. |
| Fail-Safe Receiver | Yes (bus idle / open / short fail-safe) | Yes (true fail-safe) | Fail-safe behavior ensures a defined logic state when the bus is undriven, preventing communication errors. |
| ESD Protection (Bus Pins) | ±8 kV contact / ±15 kV air (IEC 61000-4-2) | ±8 kV contact / ±15 kV air (IEC 61000-4-2) | Robust ESD protection improves reliability in electrically noisy industrial environments. |

Frequently asked questions
What are the primary functional differences between the ADM3050EBRIZ and the ADM3067ETRZ-EP-R7?
The ADM3050EBRIZ is a 5 kV rms isolated CAN FD transceiver compliant with ISO 11898-2:2016, supporting data rates up to 12 Mbps. The ADM3067ETRZ-EP-R7 is a 3.3 V to 5 V RS-485/RS-422 transceiver with ±15 kV ESD protection (IEC 61000-4-2) and data rates up to 50 Mbps, designed for enhanced product (EP) applications. They serve different bus protocols (CAN FD vs. RS-485/RS-422) and are not functionally interchangeable.
Do the ADM3050EBRIZ and ADM3067ETRZ-EP-R7 use the same package and pinout?
No. The ADM3050EBRIZ is supplied in a 16-lead SOIC_W (wide-body) package, while the ADM3067ETRZ-EP-R7 is supplied in an 8-lead SOIC_N package. Pin counts, pin functions, and PCB land patterns differ, so they cannot be dropped into the same footprint.
What are the supply voltage requirements for each device?
The ADM3050EBRIZ operates from a single 5 V supply on VCC1 (logic side) and VCC2 (bus side) with integrated isolated DC-to-DC conversion. The ADM3067ETRZ-EP-R7 operates from a 3.3 V to 5 V supply on a single VCC rail. Designs must match the respective supply architecture; the ADM3067ETRZ-EP-R7 does not provide galvanic isolation.
Does the ADM3050EBRIZ provide galvanic isolation while the ADM3067ETRZ-EP-R7 does not?
Correct. The ADM3050EBRIZ is a signal-isolated CAN FD transceiver rated for 5 kV rms isolation per UL 1577 and CSA, with reinforced isolation suitable for safety-critical and high-noise environments. The ADM3067ETRZ-EP-R7 is a non-isolated RS-485/RS-422 transceiver; any isolation required in its application must be provided externally.
What data rates and bus standards do these transceivers support?
The ADM3050EBRIZ supports CAN FD per ISO 11898-2:2016 at data rates up to 12 Mbps. The ADM3067ETRZ-EP-R7 supports RS-485/RS-422 at data rates up to 50 Mbps. The applicable bus standard and maximum data rate must be matched to the system protocol; neither device can substitute for the other's protocol.
What ESD and transient protection is specified for each part?
The ADM3067ETRZ-EP-R7 specifies ±15 kV ESD protection on the RS-485 bus pins per IEC 61000-4-2. The ADM3050EBRIZ specifies ESD protection on the CAN bus pins per the datasheet (contact and air discharge ratings per IEC 61000-4-2). Designers should consult the respective manufacturer datasheets for exact ESD, EFT, and surge ratings before finalizing protection circuitry.
Are the ADM3050EBRIZ and ADM3067ETRZ-EP-R7 qualified for the same operating temperature range?
The ADM3067ETRZ-EP-R7 is an enhanced product (EP) grade specified over the −55°C to +125°C operating temperature range. The ADM3050EBRIZ is specified over the −40°C to +125°C industrial temperature range. Applications requiring the extended −55°C low-end limit should verify the ADM3050EBRIZ's suitability against its datasheet ratings.
Can the ADM3067ETRZ-EP-R7 be used as a drop-in replacement for the ADM3050EBRIZ in a CAN FD network?
No. The ADM3067ETRZ-EP-R7 is an RS-485/RS-422 transceiver and does not implement the CAN or CAN FD physical layer defined by ISO 11898-2:2016. It cannot transmit or receive CAN FD frames, and it lacks the ADM3050EBRIZ's integrated galvanic isolation. Substitution would require a complete redesign of the bus interface.
Which device should be selected for an isolated CAN FD interface versus a high-speed RS-485 interface?
For an isolated CAN FD interface, select the ADM3050EBRIZ, which integrates 5 kV rms isolation and ISO 11898-2:2016 CAN FD transceiver functionality in a single 16-lead SOIC_W package. For a high-speed, non-isolated RS-485/RS-422 interface requiring up to 50 Mbps and ±15 kV ESD protection over −55°C to +125°C, select the ADM3067ETRZ-EP-R7 in its 8-lead SOIC_N package.
