Note 1: V_DD and V_EE absolute difference cannot exceed 13V.

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.

MXL1543B is a three driver/three reciever multiprotocal transceiver that operates from +5V single supply. The MXL1543B, along with MXL1544/MAX3175 and the MXL1344A, form a complete software-selectable data terminal equipment (DTE) or data communication equipment (DCE) interface port that supports the V.28 (RS-232),V.10/V.11 (RS-449/V.36,EIA-530,EIA-530A,X.21) and V.35 protocols. The MXL1543B transceiver can carry the high-speed clock and data signals while the MXL1544/MAX3175 carry the control signals.

MXL1543B can be terminated by the MXL1344A software selectable resistor termination network or by discrete termination networks.
