Description
General part information
LTC1349 Series
The LTC1349 is a 3-driver/5-receiver RS232 transceiver with very low supply current. In the no load condition, the supply current is only 300µA. The charge pump only requires four 0.1µF capacitors.In Shutdown mode, two receivers are kept alive and the supply current is 35µA. All RS232 outputs assume a high impedance state in Shutdown and with the power off.The LTC1349 is fully compliant with all data rate and overvoltage RS232 specifications. The transceiver can operate up to 120k baud with a 2500pF, 3kΩ load. Both driver outputs and receiver inputs can be forced to ±25V without damage, and can survive multiple ±10kV ESD strikes.ApplicationsNotebook ComputersPalmtop Computers
