DATASHEET  
3.3V Radiation Tolerant CAN Transceiver, with Listen  
Mode and Split Termination Output  
ISL72027SEH  
Features  
The Intersil ISL72027SEH is a 3.3V radiation tolerant 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.  
• DLA SMD 5962-15228  
• ESD Protection on all pins. . . . . . . . . . . . . . . . . . . . . .4kV HBM  
• Compatible with ISO11898-2  
• Operating supply range . . . . . . . . . . . . . . . . . . . . . 3.0V to 3.6V  
• Bus pin fault protection to ±20V  
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 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.  
• Undervoltage lockout  
• Cold spare: powered down devices/nodes will not affect  
active devices operating in parallel  
• Three selectable driver rise and fall times  
• Glitch free bus I/O during power-up and power-down  
• Full fail-safe (open, short, terminated/undriven) receiver  
• Hi Z input allows for 120 nodes on the bus  
• High data rates. . . . . . . . . . . . . . . . . . . . . . . . . . . . up to 5Mbps  
• Quiescent supply current . . . . . . . . . . . . . . . . . . . . 7mA (max)  
• Listen mode supply current . . . . . . . . . . . . . . . . . . 2mA (max)  
• -7V to +12V common-mode input voltage range  
• 5V tolerant logic inputs  
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 ISL72027SEH is available in an 8 Ld hermetic ceramic  
flatpack and die form that operate across the temperature  
range of the -55°C to +125°C. The logic inputs are tolerant  
with 5V systems.  
Other CAN transceivers available are the ISL72026SEH and  
ISL72028SEH. For a list of differences see Table 1 on page 2.  
• Thermal shutdown  
• Acceptance tested to 75krad(Si) (LDR) wafer-by-wafer
