GENERAL DESCRIPTION
FEATURES
o MXL1544/MAX3175, MXL1543, MXL1344A Chipset Is Pin Compatible with LTC1544, LTC1543, LTC1344A Chipset o Chipset Operates from a Single +5V Supply o Software-Selectable DCE/DTE o Supports V.28 (RS-232), V.10/V.11 (RS-449/V.36, EIA-530, EIA-530A, X.21, RS-423) Protocols o Flow-Through Pin Configuration o True Fail-Safe Operation o Low 0.5µA Shutdown Current (No-Cable Mode) o 10µs Receiver Input Deglitching (MAX3175 Only) o TUV-Certified NET1/NET2 and TBR1/TBR2 Compliant MXL1544/MAX3175 The MXL1544/MAX3175 are four-driver/four-receiver multiprotocol transceivers that operate from a single +5V supply in conjunction with the MXL1543. The MXL1544/MAX3175, along with the MXL1543 and 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, RS-423), and V.35 protocols. The MXL1544/ MAX3175 transceivers carry serial interface control signaling, while the MXL1543 carries the high-speed clock and data signals.
