The LTC1383 is an ultra-low power 2-driver/2-receiver

RS232 transceiver that operates from a single 5V

supply. The charge pump requires only four space-

saving 0.1

transceiver is only 220

µA 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, 3k

Ω load. Both

driver outputs and receiver inputs can be forced to

±25V without damage and can survive multiple ±10kV

ESD strikes.
