The ST75185C contains three drivers and five receivers. The pinout matches the DB9S connector design in order to decrease the part count, reduce the board space required and allow easy interconnection of the UART and serial port connector of IBM PC/ATTM and compatibles. The bipolar circuits and processing of the ST75185C provides a rugged low-cost solution for this function at the expense of quiescent power and external passive components relative to the ST75C185.
The ST75185C complies with the requirements of the EIA/TIA 232-E and ITU (formally CCITT) v.28 standards. These standards are for data interchange between a host computer and peripheral at signalling rates up to 20k-bits/s. The switching speeds of the ST75185C are fast enough to support rates up to 120K-bits/s with lower capacitive loads (shorter cables). Inter-operability at the higher signalling rates cannot be assured unless the designer has design control of the cable and the interface circuits at the both ends. For inter-operability at signalling rates to 120 k-bits/s, use of EIA/ITA-423-B (ITU v.10) and EIA/ITA-422-B (ITU v.11) standards are recommended.
The ST75185C is characterized for operation over the range of 0°C to 70°C.
