The LTC

RS232 transceiver that operates from a single 5V

supply. The charge pump requires only four space-

transceiver is only 220µA with driver outputs unloaded.

The LTC1383 is fully compliant with all data rate and

overvoltage RS232 specifications. The transceiver can

operate up to 120kbaud 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.
