ISL72027CSEH中文资料3.3V Radiation Hardened CAN Transceiver with Listen Mode and Split Termination Output数据手册Renesas规格书

描述 Description

The Intersil ISL72027CSEH is a radiation hardened 3.3V CAN transceiver that is compatible with the ISO 11898-2 standard for applications calling for Controller Area Network (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 of up to 5Mbps. It can drive a 40m cable at 1Mbps per the ISO 11898-2 specification. The device is designed to operate over a common-mode range of -7V to +12V, with a maximum of 120 nodes. The device 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 ISL72027CSEH 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 ISL72026CSEH and ISL72028CSEH.
