多台RS - 232驱动器和接收 MULTIPLE RS-232 DRIVERS AND RECEIVERS
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 A/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.
