DESCRIPTION
The LTC®1343 is a 4-driver/4-receiver multiprotocol transceiver that operates from a single 5V supply. Two LTC1343s form the core of a complete software-selectable DTE or DCE interface port that supports the RS232, RS449, EIA-530, EIA-530-A, V.35, V.36 or X.21 protocols. Cable termination may be implemented using the LTC1344 software-selectable cable termination chip or by using existing discrete designs.
