Transceiver ISO1050DUBR interface IC by Texas Instruments, CAN 1/1, SOP-8 package

Texas Instruments ISO1050DUBR is an interface transceiver IC designed to provide CAN physical-layer connectivity between a controller and a CAN bus. Packaged in an SOP-8 form factor, the device implements a single transmit and receive channel (CAN 1/1) and offers the necessary signal translation and protection features for board-level integration in automotive and industrial control systems. It is intended for applications that require reliable differential signaling and standard CAN bus communication at the physical layer.

Advantages

The ISO1050DUBR integrates a single-channel CAN transceiver with industry-standard physical interfaces in a compact SOP-8 package, simplifying PCB layout and allowing straightforward replacement or upgrade of CAN front-end circuitry. The device supports differential CAN signaling and provides the expected electrical characteristics for safe and stable data exchange between a microcontroller and the bus. Its single-channel design reduces component count when only one CAN node is required, helping to optimize board space and BOM complexity.

Key specifications

• Topology: single CAN transmit and receive channel (1 TX / 1 RX)
• Package: SOP-8 surface-mount package
• Function: physical-layer CAN transceiver for differential bus communication
• Application environment: automotive and industrial CAN networks
• Board integration: suitable for PCB-mounted transceiver role between controller and CAN bus

How to use

Integrate the SOP-8 transceiver onto the PCB with appropriate CAN bus termination and filtering components as required by the target network. Connect the TX and RX pins to the CAN controller or microcontroller CAN peripheral according to the device datasheet and route the CAN_H and CAN_L signals to the bus through recommended layout practices. Ensure supply decoupling and any required protection or common-mode filtering are implemented to meet system EMC and robustness targets.
