Product Summary

The tja1040t/n1 is an interface between the Controller Area Network (CAN) protocol controller and the physical bus. It is primarily intended for high speed applications, up to 1 MBaud, in passenger cars. The device provides differential transmit capability to the bus and differential receive capability to the CAN controller.

Parametrics

tja1040t/n1 absolute maximum ratings: (1)VTXD, DC voltage on pin TXD: -0.3 VCC + 0.3 V; (2)VRXD, DC voltage on pin RXD: -0.3 VCC + 0.3 V; (3)VSTB, DC voltage on pins STB: -0.3 VCC + 0.3 V; (4)Tvj, virtual junction temperature: -40 +150℃; (5)Tstg, storage temperature: -55 +150℃.

Features

tja1040t/n1 features: (1)Fully compatible with the ISO 11898 standard; (2)High speed (up to 1 MBaud); (3)Very low-current standby mode with remote wake-up capability via the bus; (4)Very low ElectroMagnetic Emission (EME); (5)Differential receiver with high common-mode range for ElectroMagnetic Immunity (EMI); (6)Transceiver in unpowered state disengages from the bus (zero load); (7)Input levels compatible with 3.3 V and 5 V devices; (8)Voltage source for stabilizing the recessive bus level if split termination is used (further improvement of EME); (9)At least 110 nodes can be connected; (10)Transmit Data (TXD) dominant time-out function; (11)Bus pins protected against transients in automotive environments; (12)Bus pins and pin SPLIT short-circuit proof to battery and ground; (13)Thermally protected.
