AMIS−
42673
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.
