Description
The ISL71026M 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. The transceiver can transmit and receive at bus speeds of up to 1Mbps. The device is designed to operate across 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 ISL71026M is available in a plastic 14 Ld TSSOP package. It operates across the temperature range of -55°C to +125°C. The logic inputs are tolerant with 5V systems.

Are the ISL71026M NC (no connect) pins floating?
Question: Pins 1, 4, 7, 8, 10, and 14 are listed as NC (no connect). Are they floating or are they connected to anything inside the device? For space applications we need to connect floating metal or NC pins to 0V (ground). Is this safe for the ISL71026M? Answer: These ...
