AMIS-42671 Datasheet | onsemi

Description The AMIS- 42671 CAN transceiver with autobaud is the interface between a controller area network (CAN) protocol controller and the physical bus. It 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 mon- mode voltage range of the receiver inputs, the AMIS- 42671 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- 42671 is primarily intended for industrial network 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 munication speed needs to be low. AMIS- 42671 allows low transmit data rates down 10 kbit/s or lower. The autobaud function allows the CAN controller to determine the ining baud rate without influencing the CAN munication on the bus. Features - Fully patible with the ISO 11898- 2 standard - Autobaud function - Wide range of bus munication speed (0 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), mon- mode choke is no longer required - Differential receiver with wide mon- mode range ($35 V) 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 patible with 3.3 V devices - ESD protection for CAN bus at $8 k V - These are Pb- Free Devices- http://onsemi.
