LTC1384 5V Low Power RS232 Transceiver with 2 Receivers Active in Shutdown

The LTC™1384 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.

The LTC1384 is fully compliant with all data rate and overvoltage RS232 specifications. The transceiver can operate up to 120kbaud with a 2500pF, 3k Ω load. Both driver outputs and receiver inputs can be forced to �25V without damage and can survive multiple ±10kV ESD strikes
