The LTC
®
2846 is a 3-driver/3-receiver multiprotocol trans-
ceiver with on-chip cable termination. When combined with
the LTC2844 or LTC2845, this chip set forms a complete
software-selectable DTE or DCE interface port that supports
the RS232, RS449, EIA530, EIA530-A, V.35, V.36 and X.21
protocols. All necessary cable termination is provided inside
the LTC2846. The LTC2846 has a boost regulator that takes
in a 3.3V input and switches at 1.2MHz, allowing the use of
tiny, low cost capacitors and inductors 2mm or less in height.
The 5V output drives an internal charge pump that requires
only five space-saving surface mounted capacitors. The
LTC2846 is available in a 36-lead SSOP surface mount
package.
