LMS202E 15KV ESD Rated, 5V Single Supply TIA/EIA-232 Dual Transceivers

Check for Samples: LMS202E

FEATURES

DESCRIPTION

The LMS202E features two transmitters and two

receivers for RS-232 communication. It has a DC-to-

DC converter that permits the device to operate with

only a single +5V power supply. The on-chip DC-to-

DC converter which utilizes four external 0.1μF

capacitors to generate dual internal power supplies

for RS-232 compatible output levels.

•

ESD Protection for RS-232 I/O Pins

•

±15kV-IEC1000 4-2 (EN61000-4-2) Contact

Discharge

•

±8kV-IEC1000 4-2 (EN61000-4-2) Air-Gap

Discharge

•

±15kV Human Body Model

The device meet EIA/TIA-232E and CCITT V.28

specifications up to 230kbits/sec. The LMS202E is

available in a 16 pin narrow and wide SOIC package.

Single +5V Power Supply

230 Kbps Data Rate

On-Board DC-to-DC Converter

0.1μF Charge Pump Capacitors

Drop-In Replacement to Maxim’s MAX202E

The transmitter outputs and receiver inputs have

±15kV electrostatic discharge (ESD) protection. The

LMS202E survives a ± 15kV ESD event to the RS-

232 input and output pins when subjected according

to Human Body Model or IEC 1000-4-2 (EN61000-4-

2), air-gap specification. It survives a ±8kV discharge

when subjected to IEC 1000-4-2 (EN61000-4-2),

contact specification. This device is designed for use

in harsh environments where ESD is a concern.

APPLICATIONS

•

POS Equipment (Bar code reader)

Hand-Held Equipment

General Purpose RS-232 Communication
