ISL71026M

3.3V CAN Transceiver, 1Mbps, Listen Mode, Loopback

Product Status: Mass Production

OVERVIEW

The ISL71026M is a radiation tolerant 3.3V CAN transceiver that is compatible with the ISO11898-2 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 up to 5Mbps. It can drive a 40m cable at 1Mbps per the ISO11898-2 specification. 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.
