Maxim Integrated MXL1543
The MXL1543 is a three-driver/three-receiver multiprotocol transceiver that operates from a +5V single supply. The MXL1543, along with the 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, EIA530A, X.21), and V.35 protocols. The MXL1543 transceivers carry the high-speed clock and data signals while the MXL1544/MAX3175 carry the control signals.

GENERAL DESCRIPTION
FEATURES
o MXL1543, MXL1544/MAX3175, and MXL1344A Chipset Is Pin Compatible with LTC1543, LTC1544, and LTC1344A o Supports RS-232, RS-449, EIA-530, EIA-530A, V.35, V.36, and X.21 o Software-Selectable Cable Termination Using the MXL1344A o Complete DTE or DCE Port with MXL1544/ MAX3175, and MXL1344A o +5V Single-Supply Operation o 0.5µA No-Cable Mode o TUV-Certified NET1/NET2 and TBR1/TBR2Compliant MXL1543 The MXL1543 can be terminated by the MXL1344A software-selectable resistor termination network or by discrete termination networks. An internal charge pump and a proprietary low-dropout transmitter output stage allow V.11- , V.28- , and V.35compliant operation from a +5V single supply. A nocable mode is entered when all mode pins (M0, M1, and M2) are pulled high or left unconnected. In nocable mode, supply current decreases to 0.5µA and all transmitter and receiver outputs are disabled (high impedance). Short-circuit current limiting and thermal shutdown circuitry protect the drivers against excessive power dissipation.
