TJA1145T,118

The TJA1145T,118 from NXP Semiconductors is a high-speed CAN transceiver that interfaces between a CAN protocol controller and a two-wire CAN bus. It is specifically designed for automotive industry applications requiring reliable differential transmit and receive capabilities.

This transceiver supports ISO 11898-2:2016 compliant CAN Partial Networking with a selective wake-up function. It features very low power consumption in Standby and Sleep modes. The device implements the CAN physical layer as defined in ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-4, enabling communication at data rates up to 2 Mbit/s.

Key electrical characteristics include a supply voltage range of 4.5V to 5.5V and an operating temperature range of -40°C to 150°C. It provides ±8 kV ESD protection on the CAN bus pins and ±6 kV ESD protection on the BAT pins. The TJA1145T,118 is housed in a 14-SOIC package and is suitable for surface mount applications.

Its features make it an ideal choice for high-speed CAN networks, especially in automotive systems where nodes are always connected to the battery but only active when required to minimize current consumption. The I/O levels automatically adjust to interface directly with 3.3 V to 5 V microcontrollers.
