DESCRIPTIO
The LTC
RS232 transceiver that operates from a single 5V
supply. The charge pump requires only four space-
saving 0.1µF capacitors. The supply current (I
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.
