Overview

The Intersil ISL72026ASEH is a radiation tolerant, 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 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 loopback test capability.

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 ISL72026ASEH is available in an 8 Ld hermetic ceramic flatpack and die form that operate across the temperature range of -55 °C to +125 °C.

Other CAN transceivers available are the ISL72027ASEH and ISL72028ASEH.
