Description The AMIS?42670 CAN transceiver is the interface between a controller area network (CAN) protocol controller and the physical bus and may be used in both 12 V and 24 V systems. 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?42670 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?42670 is the industrial version of the AMIS?30660 and 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?42670 allows low transmit data rates down 10 kbit/s or lower.
