The LTC1382 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 0.1F capacitors. The transceiver operates in one of two modes, Normal and Shutdown. In the Normal mode, ICC is only 220A 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 off and ICC drops to 0.2A. |
