TJA1441
High-speed CAN transceiver
Rev. 1 — 12 August 2020
Product data sheet
1 General description
The TJA1441 is a member of the TJA144x 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. TJA144x 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
TJA144x variants enable reliable communication in the CAN FD fast phase at data rates
up to 5 Mbit/s.
The TJA1441 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 TJA1441 to be easily retrofitted to existing applications.
An AEC-Q100 Grade 0 variant, the TJR1441, is available for high temperature
applications, supporting operation at 150 °C ambient temperature. A variant intended for
industrial applications, the TJF1441, is also available.
1.1 TJA1441 variants
The TJA1441 comes in three variants, each available in an SO8 or HVSON8 package:
• The TJA1441A 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 TJA1441B is a high-speed CAN transceiver with Normal and Silent modes.
• The TJA1441D is a high-speed CAN transceiver with Normal and Silent modes with a
transmitter/receiver On/Off input.
