The SN752232 complies with the requirements of
the TIA/EIA-232-F and ITU V.28 standards. These
standards are for data interchange between a
host computer and a peripheral at signaling rates
up to 20 kbit/s. The device supports data rates up
to 120 kbit/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 up to 120 kbit/s, use of
TIA/EIA-423-B (ITU V.10) and TIA/EIA-422-B
(ITU V.11) standards is recommended.
The SN752232 is characterized for operation over
the temperature range of 0
°
C to 70
