LMS202
5V Single Supply TIA/EIA-232 Dual Transceivers
General Description
The LMS202 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 0.1F 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 LMS202 is available in a 16 pin
narrow and Wide SOIC package.
