AMIS-42670 High-Speed CAN Transceiver
Data Sheet
For Long Networks
1.0 General 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 12V and 24V 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.
2.0 Key Features
Fully compatible with the ISO 11898-2 standard
Certified “Authentication on CAN Transceiver Conformance (d1.1)”
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 12V and 24V industrial and automotive applications
Low electromagnetic emission (EME) common-mode choke is no longer required
Differential receiver with wide common-mode range (+/- 35V) for high EMS
No disturbance of the bus lines with an un-powered node
Thermal protection
Bus pins protected against transients
Silent mode in which the transmitter is disabled
Short circuit proof to supply voltage and ground
Logic level inputs compatible with 3.3V devices
