AMIS-42675 High-Speed Low Power CAN Transceiver
For Long Networks
1.0 General Description
Data Sheet
The AMIS-42675 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 24V systems. The transceiver provides differential transmit capability to the bus and differential receive
capability to the CAN controller.
The AMIS-42675 is the low power member of the CAN high-speed transceiver family and offers the following additional features:
•
•
•
Ideal passive behaviour when supply voltage is removed
Wake-up over bus
Extremely low current standby mode
Due to the wide common-mode voltage range of the receiver inputs, the AMIS-42675 is able to reach outstanding levels of electro-
magnetic susceptibility (EMS). Similarly, extremely low electromagnetic emission (EME) is achieved by the excellent matching of the
output signals.
The AMIS-42675 is the industrial version of the AMIS-42665 and primarily 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-42675 allows low transmit data rates down 10 Kbit/s or lower.
