LINEAR INTEGRATED CIRCUIT
MULTIPLE RS-232 DRIVERS
AND RECEIVERS
TSSOP-20
„ DESCRIPTION
The UTC 75185 complies with the requirements of the
TIA/EIA232-F and ITU (formerly CCITT) v.28 standards. These
standards are for data interchange between a host computer and
peripheral at signaling rates up to 20kbit/s. The switching speeds of
the UTC 75185 are fast enough to support rates up to 120kbite/s
with lower capacitive loads (shorter cables). Interoperability at the
higher signaling rates cannot be assured unless the designer has
design control of the cable and the interface circuits at both ends.
For interoperability at signaling rates to 120kbit/s, use of
ITA/EIA-423-B (ITU v.10) and TIA/EIA-422-B (ITU v.11) standards
are recommended.
