UTC75232 LINEAR INTEGRATED CIRCUIT
MULTIPLE RS-232 DRIVERS
AND RECEIVERS
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.
FEATURES
*Single chip with easy interface between UART and
Serial-Port Connector of IBMTM, PC/ATTM and
Compatibles.
*Meets or Exceeds the Requirements of ANSI Standard
TIA/EIA-232-F and ITU Recommendation V.28
*Designed to support data rates up to 120 kbit/s
*ESD Protection to 2kV on Bus Terminals
