特点Software-Selectable Transceiver Supports: RS232, RS449, EIA530, EIA530-A, V.35, V.36, X.21TUV/Detecon Inc. Certified NET1 and NET2 Compliant (Test Report No. NET2/102201/97)TBR2 Compliant (Test Report No. CTR2/022701/98)Software-Selectable Cable Termination Using the LTC1344AComplete DTE or DCE Port with LTC1544, LTC1344AOperates from Single 5V Supply典型应用描述The LTC?1543 is a 3-driver/3-receiver multiprotocol transceiver that operates from a single 5V supply. The LTC1543 and LTC1544 form the core of a complete software-selectable DTE or DCE interface port that supports the RS232, RS449, EIA530, EIA530-A, V.35, V.36 or X.21 protocols. Cable termination may be implemented using the LTC1344A software-selectable cable termination chip or by using existing discrete designs.The LTC1543 runs from a single 5V supply using an internal charge pump that requires only five space-saving surface mounted capacitors. The part is available in a 28-lead SSOP surface mount package.
