AMIS-30663
High Speed CAN Transceiver
Data Sheet
1.0 General Description
The AMIS-30663 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 digital interface level is powered from a 3.3V supply providing true I/O voltage levels for 3.3V 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-30663 is able to reach outstanding levels of electromagnetic susceptibility. Similarly, extremely low
electromagnetic emission is achieved by the excellent matching of the output signals.
2.0 Key Features
