LTC1543IG#PBF

LTC1543 is a 3-driver/3-receiver multiprotocol transceiver that operates from a single 5V supply. It forms 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. This device runs from a single 5V supply using an internal charge pump that requires only five space-saving surface mounted capacitors. It is widely used in applications such as data networking, CSU and DSU, data routers etc.
