DESCRIPTION

The UTC 75232 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

75232 are fast enough to support rates up to 120kbit/s

with lower capacitive loads (shorter cables).

Interoperability at the higher signaling rates cannot be

expected 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

ANSI ITA/EIA-423-B (ITU V.10) and TIA/EIA-422-B

(ITU V.11) standards are recommended.

The UTC 75232 is Characterized for operation over

the temperature range of 0°C to 70°C.
