TJA1050T/H/V,112

Drivers, Receivers, Transceivers Overview

The TJA1050T/H/V,112 is a high-speed CAN transceiver manufactured by NXP Semiconductors. It interfaces between the Controller Area Network protocol controller and the physical bus, providing differential transmit and receive capabilities. The device supports data rates up to 1 Mbaud and operates within a supply voltage range of 4.75 V to 5.25 V. It features very low electromagnetic emission due to optimal matching of output signals CANH and CANL. The component includes a silent mode where the transmitter is disabled, and it lacks a standby mode. It is housed in an SO8 plastic small outline package with 8 leads.

Drivers, Receivers, Transceivers Feature Summary

• Fully compatible with ISO 11898 standard for high-speed automotive applications
• Very low electromagnetic emission (EME) resulting from optimal signal matching
• Differential receiver with wide common-mode range for high electromagnetic immunity (EMI)
• Unpowered nodes do not disturb the bus lines

Drivers, Receivers, Transceivers Applications

• High-speed automotive applications using baud rates from 60 kbaud up to 1 Mbaud
• Nodes in partially powered networks requiring power-down situations
• Interfaces between CAN protocol controllers and physical two-wire CAN buses

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and reel specifications. Ensure the component status matches production requirements. Cross-reference the datasheet revision history to confirm the version aligns with design specifications before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this transceiver for designs requiring full ISO 11898 compliance and high-speed data transmission up to 1 Mbaud. Consider its suitability for partially powered networks due to the absence of a standby mode and improved unpowered node behavior. Verify input level compatibility with 3.3 V or 5 V devices and ensure thermal protection meets system constraints.

Drivers, Receivers, Transceivers Part Context

The TJA1050 represents the third generation of Philips high-speed CAN transceivers, succeeding the PCA82C250 and PCA82C251. It offers significant improvements in electromagnetic emission reduction through optimized CANH and CANL signal matching. The device is designed to handle automotive electrical transients and provides short-circuit protection to battery and ground.
