The LTC2847CUHF#PBF is a 3-driver/3-receiver software-selectable Multiprotocol Transceiver 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 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 to interface with low voltage ASICs.
- On-chip cable termination
- Complete DTE or DCE port with LTC2845
