TJA1462
CAN FD signal improvement transceiver with Standby mode
Rev. 2 — 15 October 2021
Product data sheet
1 General description
The TJA1462 is a member of the TJA146x 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. TJA146x 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.
The TJA1462 includes CAN Signal Improvement Capability (SIC), as defined in
CiA 601-4:2019. CAN signal improvement significantly reduces signal ringing in a
network, allowing reliable CAN FD communication to function in larger topologies. In
addition, the TJA1462 features a much tighter bit timing symmetry performance to enable
CAN FD communication up to 8 Mbit/s.
The TJA1462 is intended as a simple replacement for high-speed Classical CAN
and CAN FD transceivers, such as the TJA1042 or TJA1044GT from NXP. It offers
pin compatibility and is designed to avoid changes to hardware and software design,
allowing the TJA1462 to be easily retrofitted to existing applications.
An AEC-Q100 Grade 0 variant, the TJR1462, is available for high temperature
applications, supporting operation at 150 °C ambient temperature.
1.1 TJA1462 variants
The TJA1462 comes in two variants, each available in an SO8 or HVSON8 package:
• The TJA1462A is a high-speed CAN transceiver with Normal and Standby modes and
a VIO supply pin. The VIO pin allows for direct interfacing with 3.3 V- and 5 V-supplied
microcontrollers.
• The TJA1462B is a high-speed CAN transceiver with Normal and Standby modes.
