1 / 18 page GD65232, GD75232 MULTIPLE RS232 DRIVERS AND RECEIVERS SLLS206J − MAY 1995 − REVISED NOVEMBER 2004 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Single Chip With Easy Interface Between UART and Serial-Port Connector of IBM PC/AT and Compatibles D Meet or Exceed the Requirements of TIA/EIA-232-F and ITU v.28 Standards D Designed to Support Data Rates up to 120 kbit/s D Pinout Compatible With SN75C185 and SN75185 description/ordering information The GD65232 and GD75232 combine three drivers and five receivers from the Texas Instruments 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 GD65232 and 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 GD65232 and GD75232 comply 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 these devices 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 TIA/EIA-423-B (ITU V.10) and TIA/EIA-422-B (ITU V.11) standards is recommended.
