LTC1347 5V Low Power RS232 3-Driver/5-Receiver Transceiver with 5 Receivers Active in Shutdown

The LTC®1347 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 onlyrequires four 0.1µF capacitors.

In Shutdown mode, all five receivers are kept alive and the supply current is 80µA. All RS232 outputs assume a high impedance state in Shutdown and with the power off.

The LTC1347 is fully compliant with all data rate and overvoltage RS232 specifications. The transceiver can operate up to 120kbaud with a 2500pF, 3k Ω load. Bothdriver outputs and receiver inputs can be forced to �25V without damage, and can survive multiple ±10kV ESD strikes
