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.
