Product Summary
The LTC1348CSW#TR is a 3-driver/5-receiver RS232 transceiver with very low supply current. The charge pump only requires five 0.1mF capacitors. The LTC1348CSW#TR provides full RS232 output levels when operated over a wide supply range of 3V to 5.5V The transceiver operates in one of four modes: Normal, Receiver Disable, Receiver Alive and Shutdown. In Normal or Receiver Disable mode, ICC is only 600mA at 3.3V and 800mA at 5V in the no load condition. The applications of the LTC1348CSW#TR include Notebook Computers, Palmtop Computers, Printers, Portable Instruments.
