MAX14883EASA+T

P1-P3P4-P6P7-P9P10-P11
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.

Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
For the latest package outline information and land patterns (footprints), go to www.maximintegrated.com/packages. Note that a “+”,
“#”, or “-” in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing
pertains to the package regardless of RoHS status.
