NCV7340
High Speed Low Power CAN
Transceiver
Description
The NCV7340 CAN transceiver is the interface between a
controller area network (CAN) protocol controller and the physical
bus and 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.
The NCV7340 is a new addition to the CAN high−speed transceiver
family and is an improved drop−in replacement for the AMIS−42665.
Due to the wide common−mode voltage range of the receiver inputs,
the NCV7340 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.
Features
• Compatible with the ISO 11898 Standard (ISO 11898−2, ISO
11898−5 and SAE J2284)
• Low Quiescent Current
• High Speed (up to 1 Mbps)
• Ideally Suited for 12 V and 24 V Industrial and Automotive
Applications
• Extremely Low Current Standby Mode with Wakeup via the Bus
• Low EME Common−Mode Choke is No Longer Required
• Voltage Source via VSPLIT Pin for Stabilizing the Recessive Bus
Level (Further EMC Improvement)
• No Disturbance of the Bus Lines with an Un−powered Node
• Transmit Data (TxD) Dominant Time−out Function
• Thermal Protection
• Bus Pins Protected Against Transients in an Automotive
Environment
• Bus and VSPLIT Pins Short−Circuit Proof to Supply Voltage and
Ground
• Logic Level Inputs Compatible with 3.3 V Devices
• Up to 110 Nodes can be Connected to the Same Bus in Function of
Topology
• These are Pb−Free Devices
Typical Applications
• Automotive
• Industrial Networks
