LMS202E

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

Transceivers

General Description

Features

n ESD protection for RS-232 I/O pins

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.

—

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

Discharge

—

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

15kV Human Body Model

n Single +5V power supply

n 230 kbps data rate

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

tions up to 230kbits/sec. The LMS202E is available in a 16

pin narrow and wide SOIC package.

n On-board DC-to-DC converter

n 0.1µF charge pump capacitors

n Drop-in replacement to Maxim’s MAX202E

The transmitter outputs and receiver inputs have 15kV

electrostatic discharge (ESD) protection. The LMS202E sur-

vives 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

n POS equipment (Bar code reader)

n Hand-held equipment

n General purpose RS-232 communication
