3.3V Radiation Tolerant CAN Transceiver with Listen Mode and Loopback
FN8762
Rev 3.00
August 16, 2016
The Intersil ISL72026SEH 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 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.
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 ISL72026SEH is available in an 8 Ld hermetic ceramic
flatpack and die form that operate across the temperature
range of -55°C to +125°C. The logic inputs are tolerant with
5V systems.
Other CAN transceivers available are the ISL72027SEH and
ISL72028SEH. For a list of differences see Table 1 on page 2.

FUNCTION
D CAN driver digital input. The bus states are LOW = Dominant and HIGH = Recessive. Internally tied HIGH.
GND Ground connection.
VCC System power supply input (3.0V to 3.6V). The typical voltage for the device is 3.3V.
R CAN Data Receiver Output. The bus states are LOW = Dominant and HIGH = Recessive.
RS A resistor to GND from this pin controls the rise and fall time of the CAN output waveform. Drive RS HIGH to put into Listen Mode.
CANL CAN bus line for low level output
CANH CAN bus line for high level output
LBK A HIGH on this pin places CANH and CANL pins in a high impedance state. The rest of the circuit remains active so that the TX
and RX can loopback diagnostic information. Internally tied LOW.
