LTC1338 - 5V Low Power RS232 5-Driver/3-Receiver Transceiver

In SHUTDOWN mode, the supply current is further reduced to 0.2µA. In RECEIVER ALIVE mode, all three receivers are kept alive and the supply current is 50µA. All RS232 outputs assume a high impedance state in SHUTDOWN and with the power off.

The LTC1338 is fully compliant with all data rate and overvoltage RS232 specifications. The transceiver can operate up to 120k baud with a 2500pF, 3kohms load. Both driver outputs and receiver inputs can be forced to �25V without damage, and can survive multiple ±10kV ESD strikes.

特点 Low Supply Current: 500µA 0.2µA Supply Current in SHUTDOWN 50µA Supply Current in RECEIVER ALIVE Mode ESD Protection Over ±10kV Operates from a Single 5V Supply Uses Small Capacitors: 0.1µF Operates to 120k Baud Three-State Outputs Are High Impedance When Off Output Overvoltage Does Not Force Current RS232 I/O Lines Can Be Forced to ±25V Without Damage Flowthrough Architecture 典型应用
