The LTC
®
1343 is a 4-driver/4-receiver multiprotocol trans-
ceiver 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.
The LTC1343 runs from a single 5V supply using an internal
charge pump that requires only five space saving surface mount
capacitors. The mode pins are latched internally to allow sharing
of the select lines between multiple interface ports.
Software-selectable echoed clock and loop-back modes help
eliminate the need for external glue logic between the serial
controller and line transceiver. The part features a flow-
through architecture to simplify EMI shielding and is available
in the 44-lead SSOP surface mount package.
