AMIS-30660 High Speed CAN Transceiver
Data Sheet
1.0 Key Features
• Fully compatible with the “ISO 11898-2” standard
• Certified “Authentication on CAN Transceiver
Conformance (d1.1)”
• No disturbance of the bus lines with an unpowered node
• Transmit data (TXD) dominant time-out function
• Thermal protection
• High speed (up to 1 Mbaud)
• Ideally suited for 12V and 24V industrial and automotive
applications
• Low Electromagnetic Emission (EME) common-mode-
choke is no longer required
• Bus pins protected against transients in an automotive
environment
• Power down mode in which the transmitter is disabled
• Input levels compatible with 3.3V devices
• Short-circuit proof to supply voltage & ground
• Differential receiver with wide common-mode range for
high Electro Magnetic Susceptibility (EMS) (+/- 35V)
2.0 General Description
The AMIS-30660 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-30660 is able to reach
outstanding levels of electromagnetic susceptibility.
Similarly, extremely low electromagnetic emission is
achieved by the excellent matching of the output signals.
