AMIS-42673 High Speed CAN Transceiver
Data Sheet
For Long Networks
1.0 Introduction
The AMIS-42673 CAN transceiver is the interface between a controller area network (CAN) protocol controller and the physical bus. It
may be used in both 12V and 24V systems. The digital interface level is powered from a 3.3V supply providing true I/O voltage levels
for 3.3V CAN controllers.
The transceiver provides differential transmit capability to the bus and differential receive capability to the CAN controller. Due to the
wide common-mode voltage range of the receiver inputs, the AMIS-42673 is able to reach outstanding levels of electromagnetic
susceptibility (EMS). Similarly, extremely low electromagnetic emission (EME) is achieved by the excellent matching of the output
signals.
The AMIS-42673 is primarily intended for applications where long network lengths are mandatory. Examples are elevators, in-building
networks, process control and trains. To cope with the long bus delay the communication speed needs to be low. AMIS-42673 allows
low transmit data rates down to 10 kbit/s or lower.
2.0 Key Features
True 3,3V or 5,0V logic level interface
Fully compatible with the “ISO 11898-2” standard
Wide range of bus communication speed (0 up to 1Mbit/s)
Allows low transmit data rate in networks exceeding 1 km
Ideally suited for 12V and 24V applications
Low electromagnetic emission (EME). Common-mode-choke is no longer required
Differential receiver with wide common-mode range (+/- 35V) for high electromagnetic susceptibility (EMS)
No disturbance of the bus lines with an un-powered node
Thermal protection
Bus pins protected against transients
Short circuit proof to supply voltage and ground
ESD protection for CAN bus at ± 8 kV
