Product Overview
Linear Technology LTC1338IS Low Power 5-Driver/3-Receiver RS232 Transceiver
FEATURES: 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 Back into Supplies RS232 I/O Lines Can Be Forced ± 25V Without Damage Flowthrough Architecture
The 3-receiver RS232 transceiver with very low supply current. In the no load condition, the supply current is only 500µA. The charge pump only requires four 0.1µF capacitors. In SHUTDOWN mode, the supply current is further reduced 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 to 120k baud with 2500pF, 3k load. Both driver outputs and receiver inputs can be forced ± 25V without damage, and can survive multiple ± 10kV ESD strikes.
