75185
LINEAR INTEGRATED CIRCUIT
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.
