功能描述

The LTC?1348 is a 3-driver/5-receiver RS232 transceiver with very low supply current. The charge pump only requires five 0.1μF capacitors. The LTC1348 provides full RS232 output levels when operated over a wide supply range of 3V to 5.5VThe transceiver operates in one of four modes: Normal, Receiver Disable, Receiver Alive and Shutdown. In Normal or Receiver Disable mode, ICC is only 600μA at 3.3V and 800μA at 5V in the no load condition. In Shutdown mode, the supply current is further reduced to 0.2μA. In Receiver Alive mode, all five receivers are kept alive and the supply current is 15μA. All RS232 outputs assume a high impedance state in Shutdown or Receiver Alive mode or with the power off. The receiver outputs assume a high impedance state in Receiver Disable or with the power off.The LTC1348 is fully compliant with all data rate and overvoltage RS232 specifications. The transceiver operates up to 120kbaud with all drivers loaded with 1000pF, 3kohms. Both driver outputs and receiver inputs can be forced to ?25V without damage and can survive multiple ±10kV ESD strikes.
