MULTIPLE RS-232 DRIVERS

AND RECEIVERS

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.
