ISO1042DWVR 1/1 Transceiver Full CANbus 8-SOIC
The ISO1042DWVR is a Texas Instruments galvanically isolated Controller Area Network (CAN) transceiver. As a basic-isolation member of the ISO1042 family, it bridges a CAN controller on the logic side with a 70-V fault-protected differential bus on the field side, using a silicon-dioxide (SiO2) insulation barrier rated for 5000 VRMS withstand voltage and 1060 VRMS working voltage to keep high-voltage transients and noisy bus currents away from the local ground plane . The part operates across a -40 C to +125 C ambient range, accepts a VCC1 supply from 1.71 V to 5.5 V for direct interfacing with 1.8-V, 2.5-V, 3.3-V, or 5.0-V logic, and requires a 4.5 V to 5.5 V VCC2 rail for the bus driver, making it a compact, catalog-rated building block for isolated CAN nodes in industrial and instrumentation equipment .
Typical application scenarios for the ISO1042DWVR include AC and servo motor drives, solar inverters, programmable-logic-controller (PLC) and distributed-control-system (DCS) communication modules, elevator and escalator control units, industrial power supplies, and battery charging and management systems where the CAN bus spans electrically noisy or potentially hazardous potentials . When paired with an isolated DC/DC converter, the transceiver forms a complete galvanic-isolation barrier that protects sensitive microcontrollers, FPGAs, and analog front ends from ground loops, lightning-induced surges, and short-circuit faults on long fieldbus cabling.
Alternative CAN transceive models
● ISO1042BDWVR: SOIC-8 tape-and-reel variant with reinforced isolation (7071 VPK VIOTM and 1500 VPK VIORM) for designs that must meet stricter safety-isolation requirements.
● ISO1042BQDWVRQ1: Automotive-grade, AEC-qualified reinforced-isolation SOIC-8 variant of the ISO1042 for in-vehicle CAN FD networks and automotive EMC environments.
● ISO1044: Ultra-small TI isolated CAN transceiver offered as a next-generation alternative with reduced board-space occupation, though with different isolation and bus-fault-protection trade-offs versus the ISO1042.
● ISOW1044: TI isolated CAN FD transceiver with an integrated DC/DC converter that consolidates signal and power isolation in one package to simplify isolated-node design.
● NSI1042-DSWVR: Novosense domestic isolated CAN transceiver positioned as a pin- and function-compatible replacement for the ISO1042BDWVR in cost-sensitive localization projects.
