The LTC1386 is an ultra-low power 2-driver/2-receiver

EIA/TIA562 transceiver that operates from a single

3.3V supply. The charge pump requires only four

space-saving 0.1

µF capacitors. The supply current

puts unloaded.

The LTC1386 is fully compliant with all data rate and

overvoltage EIA/TIA562 specifications. The transceiver

can operate up to 120kbaud with a 1000pF, 3k

Ω load.

Both driver outputs and receiver inputs can be forced to

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

ESD strikes.
