General Description
The MAX14883E fault-protected, high-speed Control
Area Network (CAN) transceiver is optimized for industrial
network applications. This device features ±60V fault
protection, a ±25V functional common mode input range,
and high ±10kV ESD protection (contact discharge) on
the CANH and CANL bus. The device operates from a
single 5V supply (V
CC
) and includes a logic-level supply
input (V
L
) for interfacing with 1.8V to 5V logic.
The MAX14883E features a polarity selection input (POL)
that swaps the CANH and CANL I/Os, allowing for software
correction of cross-wired field cables.
The MAX14883E operates at the maximum CAN high-
speed data rate, allowing up to 1Mbps on small networks.
The maximum speed on large networks may be limited by
capacitive loading and other factors.
The transceiver includes a transmitter dominant timeout
(t
DOM
) to prevent bus lockup caused by controller error
or by a fault on the TXD input. When TXD remains in the
dominant state (low) for longer than t
DOM
, the driver is
switched to the recessive state, releasing the bus.
The MAX14883E is available in a narrow, 8-pin SOIC
package and operates over the -40°C to +125°C
temperature range.
