LTC1384

5V Low Power RS232

Transceiver with 2 Receivers

Active in Shutdown

DESCRIPTIO

EATURE

■

Operates from a Single 5V Supply

Low Supply Current: I_CC= 220µA

I_CC= 35µA in Shutdown Mode with Both

Receivers Kept Alive

ESD Protection Over ±10kV

Uses Small Capacitors: 0.1µF

Operates to 120kBaud

Output Overvoltage Does Not Force Current

Back into Supplies

RS232 I/O Lines Can Be Forced to ±25V

Without Damage

The LTC1384 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 0.1µF capacitors.

■

Thetransceiveroperatesinoneoftwomodes, Normaland

Shutdown. In the Normal mode, I_CCis only 220µA with the

driver outputs unloaded. In the Shutdown mode, the

charge pump is turned off, the driver outputs are forced

into three-state, both receivers are kept active and I_CC

drops to 35µA. The receiver outputs may be forced into

three-state at any time using the receiver enable (EN) pin.

■

Pin Compatible with LT1180A

The LTC1384 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.
