AMIS-42673
High-Speed 3.3 V Digital
Interface CAN Transceiver
Description
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 24 V systems. The digital
interface level is powered from a 3.3 V supply providing true I/O
voltage levels for 3.3 V 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.
Features
• True 3.3 V or 5.0 V Logic Level Interface
• Fully Compatible with the “ISO 11898−2” Standard
• Wide Range of Bus Communication Speed (0 up to 1 Mbit/s)
• Allows Low Transmit Data Rate in Networks Exceeding 1 km
• Ideally Suited for 12 V and 24 V Applications
• Low Electromagnetic Emission (EME); Common−Mode−Choke is
No Longer Required
• Differential Receiver with Wide Common−Mode Range ($35 V) for
High Electromagnetic Susceptibility (EMS)
• No Disturbance of the Bus Lines with an Unpowered Node
