LTC1384 is an ultra-low power 2-driver/2-receiver RS232 transceiver that operates from a single 5V supply. The charge pump requires only four space saving 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 receiver outputs may be forced into three-state at any time using the receiver enable (RX EN) pin. It is fully compliant with all data rate and overvoltage RS232 specifications. The transceiver can operate upto 120Kbaud with a 2500pF, 3Kohm load. Both driver outputs and receiver inputs can be forced to ±25V without damage and can survive multiple ±10KV ESD strikes. It is widely used in application such as notebook computers, palmtop computers etc.
