DESCRIPTION

The ST3384E is a 3V powered EIA/TIA-232 and

V.28/V.24 communications interface with low

power requirements, high data-rate capabilities

and enhanced electrostatic discharge (ESD)

protection. All transmitter outputs and receiver

inputs are protected to ±15kV using the Human

Body Model. The ST3384E has a proprietary low

dropout transmitter output stage enabling true

RS-232 performance from 3 to 5.5V supplies with

a dual charge pump. The charge pump require

only four small 0.1µF external capacitors for

operation from a 3.3V supply.

The device is guaranteed to run at data rates of

250Kbps while maintaining RS-232 output levels.

The ST3384E has two receivers and two drivers. It

features a 1µA shutdown mode that reduces

power consumption and extends battery life in

portable systems.

Typical

applications

are

in

Notebook,

Sub-notebook, and Palmtop Computers, Battery
