Replacement verdict
Not a drop-in replacement
The ADM3050EBRIZ and ADM3065ETRZ-EP-R7 are not functionally interchangeable: the ADM3050EBRIZ is an isolated CAN transceiver, while the ADM3065ETRZ-EP-R7 is a non-isolated RS-485 transceiver. They differ in bus protocol, isolation, data rate, and package, so substitution requires a full system redesign rather than a direct swap.

Key electrical and mechanical differences between the two devices
| Parameter | ADM3050EBRIZ | ADM3065ETRZ-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 50 Mbps | Maximum signaling rate determines whether the part meets the bandwidth requirements of the bus and cabling. |
| 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 of the target system. |
| Duplex / Channel Configuration | Half-duplex CAN (single differential pair) | Half-duplex RS-485 | Duplex configuration must match the bus topology and the transceiver's role on the network. |
| Package | 20-lead SOIC (wide body) | 8-lead SOIC | Package footprint and pin count determine PCB layout compatibility and whether a drop-in replacement is possible. |
| Operating Temperature Range | -40 °C to +125 °C | -55 °C to +125 °C (EP grade) | Temperature range affects suitability for harsh environments and extended-temperature applications. |
| ESD Protection (Bus Pins) | ±8 kV contact / ±15 kV air (IEC 61000-4-2) | ±8 kV contact / ±15 kV air (IEC 61000-4-2) | Bus-pin ESD robustness influences field reliability and the need for external protection components. |
| Fail-Safe Receiver | Yes (CAN dominant/recessive handling) | Yes (open/short fail-safe) | Fail-safe behavior ensures a defined logic state when the bus is idle, open, or shorted, preventing indeterminate outputs. |

Frequently asked questions
What are the primary functional differences between the ADM3050EBRIZ and the ADM3065ETRZ-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 ADM3065ETRZ-EP-R7 is a 3.3 V, non-isolated RS-485/RS-422 transceiver with ±15 kV ESD protection (IEC 61000-4-2) and data rates up to 50 Mbps. The ADM3050EBRIZ integrates galvanic isolation for CAN bus applications, while the ADM3065ETRZ-EP-R7 is a non-isolated RS-485 transceiver without isolation.
Are the ADM3050EBRIZ and ADM3065ETRZ-EP-R7 pin-to-pin compatible?
No. The ADM3050EBRIZ is supplied in a 16-lead SOIC_W package (R-16-2), while the ADM3065ETRZ-EP-R7 is supplied in an 8-lead SOIC_N package (R-8). The pin counts, pin functions, and package footprints differ, so they are not pin-to-pin compatible and cannot be directly substituted on the same PCB land pattern.
What are the supported data rates for each device?
The ADM3050EBRIZ supports CAN FD data rates up to 12 Mbps, per its datasheet. The ADM3065ETRZ-EP-R7 supports RS-485/RS-422 data rates up to 50 Mbps. The applicable data rate depends on the bus protocol and cable/termination design.
What isolation rating does the ADM3050EBRIZ provide, and does the ADM3065ETRZ-EP-R7 provide isolation?
The ADM3050EBRIZ provides 5 kV rms galvanic isolation (per UL 1577) between the logic side and the CAN bus side. The ADM3065ETRZ-EP-R7 is a non-isolated RS-485/RS-422 transceiver and does not provide galvanic isolation; system-level isolation would need to be added externally if required.
What supply voltages do the ADM3050EBRIZ and ADM3065ETRZ-EP-R7 require?
The ADM3050EBRIZ operates from a single 5 V supply (VCC = 4.5 V to 5.5 V) on the logic side and an isolated 5 V supply (VIO = 4.5 V to 5.5 V) on the bus side, per its datasheet. The ADM3065ETRZ-EP-R7 operates from a single 3.3 V supply (VCC = 3.0 V to 3.6 V). Supply voltage compatibility must be verified against the target design.
What ESD protection is specified for the ADM3065ETRZ-EP-R7?
The ADM3065ETRZ-EP-R7 specifies ±15 kV ESD protection on the RS-485/RS-422 bus pins per IEC 61000-4-2 (contact and air discharge), and ±15 kV per Human Body Model (HBM) on the bus pins, as stated in its datasheet. The ADM3050EBRIZ datasheet specifies ESD ratings for its CAN bus pins; designers should consult the respective datasheets for exact ESD test conditions and levels.
Which device is better suited for isolated CAN bus applications?
The ADM3050EBRIZ is the appropriate choice for isolated CAN FD applications because it integrates 5 kV rms galvanic isolation and ISO 11898-2:2016-compliant CAN FD transceiver functionality in a single package. The ADM3065ETRZ-EP-R7 is an RS-485/RS-422 transceiver and is not intended for CAN bus protocols.
What are the operating temperature ranges for the ADM3050EBRIZ and ADM3065ETRZ-EP-R7?
The ADM3050EBRIZ is specified for the industrial temperature range of −40°C to +125°C. The ADM3065ETRZ-EP-R7 is specified for the extended temperature range of −40°C to +125°C (EP grade). Both ranges should be confirmed against the latest manufacturer datasheet revision for the specific orderable part number.
