The TJA1055T/3/CM,118 is a part of a range of differential transceiver devices from NXP Semiconductors that have been designed for reliable data communications over bus lines as well as easy connection of microcontrollers to a broad range of serial buses. This unit offers a wide input common mode voltage range, high-input impedance and fast data transmission speeds up to 500kbits/s.

The TJA1055T/3/CM,118 has a variety of application fields:

• Automotive applications, such as the transmission of control signals in powertrain, body, and infotainment applications
• Industrial control, such as process control and robotics
• Telecommunications
• General purpose serial data communications
• Flat panel display connections, such as in digital TVs, monitors, and mobile devices

The device combines the functions of an RS-485 differential line driver and receiver. The device has an enable input which allows the user to enable or disable the driver and receiver circuits. When the enable bit is low, the output driver is turned off and the input receiver is placed in a high impedance state, thereby disconnecting the TJA1055T/3/CM,118 from the bus.

The TJA1055T/3/CM,118 ensures reliable data communications over bus lines with its built-in fault protection features. It has overload protection with temperature dependent current limitation and a disable function that disconnects the device from the bus when an overload is detected. It also has short circuit protection and short-to-ground protection by current limiting.

The TJA1055T/3/CM,118 is designed to operate at data rates up to 500kbits/s, and its differential common-mode input range extends from -7V to +12V, with a guaranteed data rate of 100kbits/s. The receiver input resistance of the TJA1055T/3/CM,118 is typically greater than 10kΩ and can withstand input common-mode voltages of up to -7V to +12V.

This device features an active ESD protection on the receiver inputs to protect them against electrostatic discharges (ESD). The receiver inputs are clamped to a maximum of +/-7.5V when the ESD is applied. This ensures the device is not damaged and reliability is maintained.

The TJA1055T/3/CM,118 is an ideal solution for automotive, industrial control, and general purpose serial data communications. It is a dependable transceiver device that offers reliable data communications and fault protection features. With its wide common mode voltage range and high-input impedance, it is a cost effective solution for a variety of applications.
