The Intersil ISL72026CSEH is a radiation hardened,
3.3V CAN transceiver that is compatible with the
Features
• Electrically screened to SMD 5962-15228
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.
• 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
• Undervoltage lockout
This device 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 Loopback test capability.
• Cold spare: powered down devices/nodes do not
affect active devices operating in parallel
• Three selectable driver rise and fall times:
• Fast speed (RS = 0V) - edges and propagation
delays optimized for data rate of 1Mbps
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.
• Medium speed (RS = 10kΩ) - edges and
propagation delays optimized for data rate of
500kbps
The ISL72026CSEH is available in an 8 Ld hermetic
ceramic flatpack and die form that operate across the
temperature range of -55°C to +125°C.
• Slow speed (RS = 50kΩ) - edges and propagation
delays optimized for data rate of 250kbps
Other CAN transceivers available are the
ISL72027CSEH and the ISL72028CSEH. For a list of
differences between these devices, refer to Table 1 on
page 4.
• Full fail-safe (open, short, terminated/undriven)
receiver
• Hi-Z input allows for 120 nodes on the bus
• High data rates: up to 5Mbps
