Product Details

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 (VCC) and includes a logic-level supply input (VL) 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 (tDOM) 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 tDOM, 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.
