в–  DESCRIPTIO The LTCВ®2847 is a 3-driver/3-receiver multiprotocol transceiver with on-chip cable termination. When combined with
the LTC2845, this chip set forms a complete softwareselectable 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 VCC supplies the drivers, the receivers and an internal
charge pump that requires only five space-saving surface
mounted capacitors. The VIN supply drives the digital interface circuitry including the receiver output drivers. It can be
tied to VCC 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 Г— 7mm QFN package. Software-Selectable Transceiver Supports:
RS232, RS449, EIA530, EIA530-A, V.35, V.36, X.21
Operates from Single 5V Supply
Separate Supply Pin for Digital Interface Works
