TJA1040T/V,118

Drivers, Receivers, Transceivers Overview

The TJA1040T/V,118 is a high-speed CAN transceiver designed for passenger car applications up to 1 MBaud. It interfaces the CAN protocol controller with the physical bus, providing differential transmit and receive capabilities. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports input levels compatible with both 3.3 V and 5 V devices. It features a very low-current standby mode (5 μA to 15 μA) with remote wake-up capability via the bus. The component includes a TXD dominant time-out function, thermal protection, and bus pins protected against automotive transients. It is housed in an 8-lead SO plastic small outline package.

Drivers, Receivers, Transceivers Feature Summary

• Very low-current standby mode with remote wake-up capability via the bus
• Ideal passive behavior when supply voltage is off, disengaging from the bus
• Low ElectroMagnetic Emission (EME) and high ElectroMagnetic Immunity (EMI)
• Bus pins protected against transients in automotive environments

Drivers, Receivers, Transceivers Applications

• High speed Controller Area Network (CAN) applications in passenger cars
• Nodes requiring power-down or standby modes in partially powered networks
• Interfaces between CAN protocol controllers and physical two-wire CAN buses

Drivers, Receivers, Transceivers Selection Notes

Select this component for high-speed CAN communication in automotive environments where low electromagnetic emission is critical. Ensure the design accommodates the 4.75 V to 5.25 V supply voltage range. Consider the 8-lead SO package dimensions for PCB layout. Verify compatibility with the microcontroller's logic levels, as the device supports both 3.3 V and 5 V inputs.

Drivers, Receivers, Transceivers Part Context

The TJA1040 serves as an upgrade to the TJA1050 high-speed CAN transceiver while maintaining pin compatibility. It offers enhanced EMC performance and introduces a low-current standby mode with remote wake-up functionality. This makes it suitable for nodes that need to enter power-down states in partially powered networks without losing the ability to be awakened by bus activity.

Drivers, Receivers, Transceivers Replacement Considerations

The TJA1040 is pin-compatible with the TJA1050. For higher data rates supporting CAN FD up to 5 Mbit/s, consider the TJA1042. For secure CAN applications, refer to the TJA1152.
