IFX1040SJXUMA1

Overview

The IFX1040SJ is a high-speed CAN transceiver in a PG-DSO-8 package, supporting data rates up to 1 MBaud and compatible with ISO 11898-2 and ISO 11898-5. It operates on a 4.75 V to 5.25 V supply with current consumption of 6 mA (recessive) and 70 mA (dominant). The device features a standby mode with 30 µA maximum current, remote wake-up via the CAN bus, and split termination for recessive level stabilization. It includes TxD time-out, overtemperature protection, and ESD ratings of 6 kV.

Feature Summary

• Supports remote wake-up from low power standby mode via CAN bus signals
• Integrates split termination circuitry to stabilize the recessive voltage level
• Includes TxD time-out function to prevent permanent bus blocking
• Provides overtemperature protection with automatic driver deactivation

Applications

• Industrial applications requiring high-speed differential mode data transmission
• Networks with partially un-powered nodes utilizing remote wake-up capabilities
• Systems requiring reduced electromagnetic emission through slope symmetry control

Procurement Notes

Verify component authenticity and datasheet revision status before integration. Confirm that the PG-DSO-8 package dimensions align with the target PCB footprint. Ensure the design accommodates the required 100 nF decoupling capacitor at the VCC pin for stable operation within the specified voltage range.

Selection Notes

Select this component when a 5 V logic interface is required for CAN networks operating up to 1 MBaud. It is suitable for environments needing robust EMI immunity and low standby current. Verify that the application does not exceed the 125 °C junction temperature limit during normal dominant state operation.

Part Context

The IFX1040SJ belongs to the standard power CAN transceiver family designed for industrial use. It provides a physical layer interface between microcontrollers and the CAN bus. The device ensures reliable communication through fail-safe mechanisms and high common-mode rejection capabilities.

Replacement Considerations

Public confirmed substitute part numbers include MAX13021ASA/V+T and MCP2003A-E/SN.
