UTC 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.
The UTC 75185 is Characterized for operation over
the temperature range of 0擄C to 70擄C.
