The TJA1081TS,112, which is an enhanced CAN transceiver, is a device used to bring the signaling level of a physical CAN bus in line with the required TTL logic levels that the microcontroller needs. By sensing the bus voltage and comparing it with its reference voltage, the device generates the appropriate signals for each side of the bus, allowing digital information to be exchanged over the physical bus.

The TJA1081TS,112 is an ideal device for digital communication applications or for use in industrial environments, being based on a robust physical layer and offering reliable data transmission. It is designed to meet the requirements of ISO 11898-2-3, which is the standard for CAN communication. This CAN transceiver is provided with several features such as protection against short-circuit, and protection against slew-rate violations at the bus terminals.

The operating temperature range of this CAN transceiver is between -40° C and 125° C, offering high immunity to thermal shocks while providing high reliability in harsh environments. It also has a wide supply voltage range between 4.5 and 5.5, making it suitable for both high voltage and low voltage applications. Furthermore, the device utilizes a Low Power Shut Down (LPSD) mode, offering very low power consumption during standby operations and providing an efficient way of prolonging battery life.

The TJA1081TS,112 is built upon an Enhanced Medium Access Control (EMAC) protocol, allowing distributed control of different nodes in the CAN bus network. It grants access to the CAN network during idle periods and features error detection and detection of stucked-at-dominant or stuck-at-recessive states. Also, the device offers voltage limitation to maintain valid bus voltage levels during transient conditions.

In addition, this device incorporates a self-wakeup mechanism to reduce the current consumption when operating in LPSD mode. The sleep wake-up sequences are controlled by two signals SlaveWN and Sleep, which trigger the Wake-up interrupt function. The timing diagram for the wakeup and subsequent wake-up must comply with the requirements of the ISO 11898-2-3 protocol.

A key feature of the TJA1081TS,112 is its built-in immunity measures against electrical interference. It includes built-in surge protection which prevents signal corruption due to electrostatic discharge (ESD). It can also withstand EFT pulses without affecting signal integrity, preserving the communication over the CAN bus.

Overall, the TJA1081TS,112 is a robust CAN transceiver which offers reliable data transmission with various features for use in industrial or digital applications. It is designed to meet the requirements of the ISO 11898-2-3 standard, utilizing an enhanced EMAC protocol, and granting access to the CAN network during idle states. The device also provides protection against ESD and EFT pulses, ensuring a reliable and secure communication over the CAN bus.
