LTC1337 - 5V Low Power RS232 3-Driver/5-Receiver Transceiver

The LTC1337 is a 3-driver/ 5-receiver RS232 transceiver with very low supply current. In the no load condition, the supply current is only 300A. The Charge Pump only requires four 0.1F capacitors and CAN supply up to 12mA of extra current to power external circuitry. In Shutdown mode, the supply current is further reduced to 1A. All RS232 outputs assume a high impedance state in Shutdown and with the power off. The LTC1337 is fully compliant with all data rate and overvoltage RS232 specifications. The transceiver CAN operate up to 120k baud with a 1000pF// 3kOhm load. Both driver outputs and receiver inputs CAN be forced to 25V without damage, and CAN survive multiple 10kV ESD strikes.
