Product data sheet
1. General description
The TJF1051 is a high-speed CAN transceiver that provides an interface between a
Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus.
The transceiver is designed for high-speed (up to 1 Mbit/s) CAN industrial applications,
providing differential transmit and receive capability to (a microcontroller with) a CAN
protocol controller.
The TJF1051 is a step up from the TJA1050 high-speed CAN transceiver. It offers
improved ElectroMagnetic Compatibility (EMC) and ElectroStatic Discharge (ESD)
performance, and also features ideal passive behavior to the CAN bus when the supply
voltage is off.
The TJF1051 can be interfaced directly to microcontrollers with supply voltages from
3 V to 5 V
These features make the TJF1051 an excellent choice for all types of HS-CAN networks,
in nodes that do not require a standby mode with wake-up capability via the bus.
