LTC2847IUHF#PBF

LTC2847 is a 3-driver/3-receiver 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 device. 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. It is widely used in application such as data networking, CSU and DSU, data routers.

• Operates from single 5V supply
• Separate supply pin for digital interface works down to 3V
• VCC supply current is 14mA typ at ( RS530, RS530-A, X.21 modes, no load)
• Rise or fall time is 15ns typical at ( TA = 25°C, VCC = 5V, VIN = 3.3V)
• Slew rate (V.28 driver) is 30V/µs maximum at ( RL = 7K, CL = 0)
• Positive charge pump output voltage is 9.3V typical at (V.11 or V.28 mode, no load)
• Operating temperature is -40°C to 85°C
• Package style is 38-lead plastic QFN
