Product Summary
The LTC1384CSW#TR is an ultra-low power 2-driver/2-receiver RS232 transceiver that operates from a single 5V supply. The charge pump requires only four spacesaving 0.1μF capacitors. The transceiver operates in one of two modes, Normal and Shutdown. In the Normal mode, ICC is only 220μA with the driver outputs unloaded. In the Shutdown mode, the charge pump is turned off, the driver outputs are forced into three-state, both receivers are kept active and ICC drops to 35μA. The applications of the LTC1384CSW#TR include Notebook Computers, Palmtop Computers.
