LMS202E 15KV ESD Rated, 5V Single Supply TIA/EIA-232 Dual Transceivers
March 2003
LMS202E
15KV ESD Rated, 5V Single Supply TIA/EIA-232 Dual
Transceivers
General 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 0.1碌F capacitors to generate dual internal power
supplies for RS-232 compatible output levels.
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.
The transmitter outputs and receiver inputs have
鹵
15kV
electrostatic discharge (ESD) protection. The LMS202E sur-
vives a
鹵
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
鹵
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.
