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 ST75185 are fast enough  
to support rates up to 120K-bits/s with lower  
capacitive loads (shorter cables). Interoperability  
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 interoperability 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.  
DESCRIPTION  
The ST75185 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/AT and compatibles. The  
bipolar circuits and processing of the ST75185  
provides a rugged low-cost solution for this  
function at the expense of quiescent power and  
external passive components relative to the  
ST75C185.  
The ST75185 is characterized for operation over  
the range of 0oC to 70oC.  
The ST75185 complies with the requirements of  
the EIA/TIA 232-E and ITU (formally CCITT) v.28
