The LTC
®
2847 is a 3-driver/3-receiver multiprotocol trans-
ceiver with on-chip cable termination. When combined with
the 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 LTC2847.
The V
CC
supplies the drivers, the receivers and an internal
charge pump that requires only five space-saving surface
mounted capacitors. The V
IN
supply drives the digital inter-
face circuitry including the receiver output drivers. It can be
tied to V
CC
or be powered off a lower supply (down to 3V) to
interface with low voltage ASICs. The LTC2847 is available in
a 0.8mm tall, 5mm
×
7mm QFN package.
