HI-3000H, HI-3001H
1Mbps Avionics CAN Transceiver
with High Operating Temperature
GENERAL DESCRIPTION
The HI-3000H is a 1 Mbps Controller Area Network
(CAN) transceiver optimized for use in high temperature
avionics applications. The device is capable of operating
at extended temperature ranges of -55°C to 175°C for
plastic packages and -55°C to 200°C for the ceramic
CERDIP-8 package. It interfaces between a CAN proto-
col controller and the physical wires of the bus in a CAN
network. Differential output amplitude and current drive
capability are specifically enhanced to meet the needs of
long cable runs typical of avionics applications.
The HI-3000H supports two modes of operation: Normal
Mode and Standby Mode. The Standby Mode is a very
low-current mode which continues to monitor bus activity
and allows an external controller to manage wake-up.
Superior common-mode receiver performance makes
the device especially suitable for applications where
ground reference voltages may vary from point to point
over long distances along the CAN bus. In addition, the
HI-3000H provides a SPLIT pin to give an output refer-
ence voltage of VDD/2 which can be used for stabilizing
the recessive bus level when the split termination tech-
nique is used to terminate the bus.
A TXD dominant time-out feature protects the bus from
being driven into a permanent dominant state (so-called
“babbling idiot”) if pin TXD becomes permanently low due
to application failure.
The device also has short circuit protection to +/-58V on
CANH, CANL and SPLIT pins and ESD protection to
+/- 6kV on all pins.
The HI-3001H is identical to the HI-3000H except the
SPLIT pin is substituted with a VIO supply voltage pin.
This allows the HI-3001H to interface directly with con-
trollers with 3.3V supply voltages.
