LTC1545 Software-Selectable Multiprotocol Transceiver Features s s DESCRIPTIO s s s s Software-Selectable Transceiver Supports: RS232, RS449, EIA530, EIA530-A, V.35, V.36, X.21 TUV/Detecon Inc. Certified NET1 and NET2 pliant (Test Report No. NET2/071601/98) TBR2 pliant (Test Report No. CTR2/071601/98) Software-Selectable Cable Termination Using the LTC1344A plete DTE or DCE Port with LTC1543, LTC1344A Operates from Single 5V Supply with LTC1543 U APPLICATIO S s s s The LTC®1545 is a 5-driver/5-receiver multiprotocol transceiver. The LTC1545 and LTC1543 form the core of a plete 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 LTC1545 runs from a 5V supply and the charge pump on the LTC1543. The part is available in a 36-lead SSOP surface mount package.
