LTC2845 - 3.3V Software-Selectable Mutiprotocol Transceiver

The LTC2845 is a 5-driver/5-receiver multiprotocol transceiver. The LTC2845 and LTC2846 form 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.

The LTC2845 operates from a 3.3V supply and supplies provided by the LTC2846. This part is available in a 36-lead SSOP and 38-lead (7mm x 5mm) QFN package. The LTC2845 and LTC2847 in QFN packages offer the smallest multiprotocol serial port available.
