DATASHEET ISL72026SEH FN8762 Rev 3.00 3.3V Radiation Tolerant CAN Transceiver with Listen Mode and Loopback August 16, 2016 The Intersil ISL72026SEH is a radiation tolerant 3.3V CAN Features transceiver that is compatible with the ISO11898-2 standard Electrically screened to SMD 5962-15228 for applications calling for Controller Area Network (CAN) serial communication in satellites and aerospace communications ESD protection on all pins 4kV HBM and telemetry data processing in harsh industrial Compatible with ISO11898-2 environments. Operating supply range . 3.0V to 3.6V The transceiver can transmit and receive at bus speeds up to Bus pin fault protection to 20V 5Mbps. It can drive a 40m cable at 1Mbps per the ISO11898-2 specification. The device is designed to operate over a Undervoltage lockout common-mode range of -7V to +12V with a maximum of 120 Cold spare: powered down devices/nodes will not affect nodes. The device has three discrete selectable driver rise/fall active devices operating in parallel time options, a listen mode feature and loopback test capability. Three selectable driver rise and fall times Receiver (Rx) inputs feature a full fail-safe design, which Glitch free bus I/O during power-up and power-down ensures a logic high Rx output if the Rx inputs are floating, shorted, or terminated but undriven. Full fail-safe (open, short, terminated/undriven) receiver Hi Z input allows for 120 nodes on the bus The ISL72026SEH is available in an 8 Ld hermetic ceramic flatpack and die form that operate across the temperature High data rates . up to 5Mbps range of -55C to +125C. The logic inputs are tolerant with Quiescent supply current 7mA (max) 5V systems. Listen mode supply current 2mA (max) Other CAN transceivers available are the ISL72027SEH and -7V to +12V common mode input voltage range ISL72028SEH.
