The GD75323DWR combines five drivers and three receivers from the trade-standard SN75188 and SN75189 bipolar quadruple drivers and receivers, respectively. The flow-through design of the GD75323DWR decreases the part count, reduces the board space required, and allows easy interconnection of the UART and serial-port connector. The all-bipolar circuits and processing of the GD75323DWR provide a rugged, low-cost solution for this function.
The GD75323DWR complies with the requirements of the ANSI 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 signal rates up to 20 kbit/s. The switching speeds of the GD75323DWR 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 assured 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 Standard TIA/EIA-423-B and TIA/EIA-422-B and ITU Recommendations V.10 and V.11 are recommended.
The GD75323DWR is characterized for operation over a temperature range of 0°C to 70°C.
