DESCRIPTIO
The LTC
ceiver that operates from a single 5V supply. The LTC1543
and LTC1544 form the core of a complete software-select-
able 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 exist-
ing 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.
