High-Speed CAN Transceiver
Features
• Supports 1 Mb/s operation
• Implements ISO-11898 standard physical layer
requirements
• Suitable for 12V and 24V systems
• Externally-controlled slope for reduced RFI
emissions
• Detection of ground fault (permanent dominant)
on TXD input
• Power-on reset and voltage brown-out protection
• An unpowered node or brown-out event will not
disturb the CAN bus
• Low current standby operation
• Protection against damage due to short-circuit
conditions (positive or negative battery voltage)
• Protection against high-voltage transients
• Automatic thermal shutdown protection
• Up to 112 nodes can be connected
• High noise immunity due to differential bus
implementation
• Temperature ranges:
- Industrial (I): -40°C to +85°C
- Extended (E): -40°C to +125°C
