AMIS-42670
High-Speed CAN
Transceiver for Long
Networks
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.
Features
• Fully Compatible with the ISO 11898−2 Standard
• Certified “Authentication on CAN Transceiver Conformance (d1.1)”
• Wide Range of Bus Communication Speed (0 Mbit/s up to 1 Mbit/s)
• Allows Low Transmit Data Rate in Networks Exceeding 1 km
• Ideally Suited for 12 V and 24 V Industrial and Automotive
Applications
• Low Electromagnetic Emission (EME) Common−Mode Choke is No

• Differential Receiver with Wide Common−Mode Range ($35 V) for
High EMS
• No Disturbance of the Bus Lines with an Unpowered 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 3.3 V Devices
• These are Pb−Free Devices*
