description
The GD75232 combines three drivers and five receivers from TI™ trade-standard SN75188 and SN75189
bipolar quadruple drivers and receivers, respectively. The pinout matches the flow-through design of the
SN75C185 to decrease the part count, reduce the board space required, and allow easy interconnection of the
UART and serial-port connector of an IBM™ PC/AT ™ and compatibles. The bipolar circuits and processing of
the GD75232 provide a rugged, low-cost solution for this function at the expense of quiescent power and
external passive components relative to the SN75C185.
The GD75232 complies with the requirements of the TIA/EIA-232-F and ITU (formerly CCITT) 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 switching speeds of the GD75232 are fast enough to support 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 ANSI TIA/EIA-423-B (ITU V.10) and TIA/EIA-422-B (ITU V.11) standards is
recommended.
The GD75232 is characterized for operation over the temperature range of 0°C to 70°C.
