3.3V Micropower EIA/TIA-562

Transceiver

DESCRIPTIO

EATURE

■

The LTC1327 is an advanced low power, three-driver/five-

receiver EIA/TIA-562 transceiver. In the no load condition,

the supply current is only 300µA. The charge pump only

requires four 0.1µF capacitors.

0.2µA Supply Current in SHUTDOWN

ESD Protection

Operates From a Single 3.3V Supply

Uses Small Capacitors

In SHUTDOWN mode, the supply current is further re-

duced to 0.2µA. All EIA/TIA-562 outputs assume a high

impedance state in SHUTDOWN and with the power off.

Operates To 120k Baud

Three-State Outputs are High Impedance When Off

Output Overvoltage Does Not Force Current Back

Into Supplies

The LTC1327 is fully compliant with all data rate and

overvoltage EIA/TIA-562 specifications. The transceiver

can operate up to 120k Baud with a 1000pF//3kΩ load.

Both driver outputs and receiver inputs can be forced to

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

ESD strikes.
