描述
The ISL72027ASEH is a 3.3V, radiation tolerant Controller Area Network (CAN) transceiver that is compatible with the ISO 11898-2 standard for applications requiring CAN serial communication in satellites and aerospace communications and telemetry data processing in harsh industrial environments.
This device can transmit and receive at bus speeds up to 5Mbps. It can drive a 40m cable at 1Mbps according to the ISO 11898-2 specification. The device is designed to operate across a common-mode range of -7V to +12V, with a maximum of 120 nodes. It has three discrete selectable driver rise/fall time options, a listen mode feature, and a split termination output.
The receiver (Rx) inputs feature a “full fail-safe” design, which ensures a logic high Rx output if the Rx inputs are floating, shorted, or terminated but undriven.
The ISL72027ASEH is available in an 8 Ld hermetic ceramic flatpack and die form that operates across the temperature range of -55°C to +125°C. The logic inputs are tolerant with 5V systems.
Other CAN transceivers available are the ISL72026ASEH and ISL72028ASEH.
