NXP TJA1040T High-Speed CAN Transceiver IC, SOIC-8, 1 Mbaud

The NXP TJA1040T/CM,118 is a high-speed Controller Area Network (CAN) transceiver, serving as the critical interface between a CAN protocol controller and the physical bus. Designed for demanding automotive applications, it supports data rates up to 1 Mbaud, making it ideal for passenger cars and other high-speed communication networks. This device provides robust differential transmit capability to the bus and differential receive capability back to the controller, ensuring reliable data transmission even in electrically noisy environments.

As the advanced successor to the TJA1050, the TJA1040T is pin-compatible and delivers superior performance. It features an ideal passive behaviour when the supply voltage is off, completely disengaging from the bus to present zero load. A key innovation is its very low-current standby mode with remote wake-up capability via the bus, making it perfect for nodes that operate in power-down or standby modes within partially powered networks.

Key Features & Benefits

• Standby Mode with Wake-Up: Enables significant power savings in electronic control units (ECUs) while remaining responsive to network activity.
• Excellent EMC Performance: Offers very low electromagnetic emissions (EME) and features a differential receiver with a high common-mode range for enhanced electromagnetic immunity (EMI).
• Robust & Protected Design: Bus pins are protected against automotive transients, are thermally protected, and are short-circuit proof to battery and ground.
• Broad Compatibility: Input levels are compatible with both 3.3V and 5V devices, and the transceiver is fully compliant with the ISO 11898 standard. It supports the connection of at least 110 nodes on a single bus.
• Integrated Safety: Includes a Transmit Data (TXD) dominant time-out function for added communication reliability.

This transceiver is supplied in a compact 8-pin SOIC (SO)
