Typical Application

Description

The LTC®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 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 interface 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 x 7mm QFN package
