Product Summary

The LTC1338ISW#TR is a 5-driver/3-receiver RS232 transceiver with very low supply current. In the no load condition, the supply current is only 500mA. The charge pump only requires four 0.1mF capacitors. In SHUTDOWN mode, the supply current is further reduced to 0.2mA. In RECEIVER ALIVE mode, all three receivers are kept alive and the supply current is 50mA. All RS232 outputs assume a high impedance state in SHUTDOWN and with the power off. The applications of the LTC1338ISW#TR include Battery-Powered Modems, Battery-Powered DCE, Notebook Computers, Palmtop Computers.
