TJR1441

High-speed CAN transceiver

Rev. 1 — 7 September 2020

Product data sheet

1 General description

The TJR1441 is a member of the TJR144x family of transceivers that provide an

interface between a Controller Area Network (CAN) or CAN FD (Flexible Data rate)

protocol controller and the physical two-wire CAN bus. TJR144x transceivers implement

the CAN physical layer as defined in ISO 11898-2:2016 and SAE J2284-1 to SAE

J2284-5, and are fully interoperable with high-speed Classical CAN and CAN FD

transceivers. All TJR144x variants enable reliable communication in the CAN FD fast

phase at data rates up to 5 Mbit/s and are qualified to AEC-Q100 Grade 0, supporting

operation at 150 °C ambient temperature.

The TJR1441 is intended as a simple replacement for high-speed Classical CAN

and CAN FD transceivers, such as the TJA1051 or TJA1057 from NXP. It offers pin

compatibility and is designed to avoid changes to hardware and software design,

allowing the TJR1441 to be easily retrofitted to existing applications.

An AEC-Q100 Grade 1 variant, the TJA1441, is available to support operation at 125 °C

ambient temperature. A variant intended for industrial applications, the TJF1441, is also

available.

1.1 TJR1441 variants

The TJR1441 comes in three variants, each available in an SO8 or HVSON8 package:

• The TJR1441A is a high-speed CAN transceiver with Normal and Silent modes and a

VIO supply pin. The VIO pin allows for direct interfacing with 3.3 V and 5 V-supplied

microcontrollers.

• The TJR1441B is a high-speed CAN transceiver with Normal and Silent modes.

• The TJR1441D is a high-speed CAN transceiver with Normal and Silent modes with a

transmitter/receiver On/Off input.

2 Features and benefits

2.1 General

• ISO 11898-2:2016, SAE J2284-1 to SAE J2284-5 and SAE J1939-14 compliant

• Standard CAN and CAN FD data bit rates up to 5 Mbit/s

• Low Electromagnetic Emission (EME) and high Electromagnetic Immunity (EMI)

• Qualified according to AEC-Q100 Grade 0

• Silent mode for node diagnosis and failure containment

• TJR1441A only: VIO input for interfacing with 3.3 V to 5 V microcontrollers

• TJR1441D only: dedicated input for switching to very low-current Off mode and

disengaging from the bus
