DESCRIPTION/ORDERING INFORMATION  
The SN75185 combines three drivers and five  
receivers from the TI 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 IBM™  
PC/AT™ and compatibles. The bipolar circuits and  
processing of the SN75185 provide a rugged low-cost  
solution for this function at the expense of quiescent  
power and external passive components relative to  
the SN75C185.

The SN75185 complies with the requirements of the  
TIA/EIA-232-F and ITU v.28 standards. These  
standards are for data interchange between a host  
computer and peripheral at signaling rates up to 20  
kbit/s. The switching speeds of the SN75185 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 to 120 kbit/s, use of TIA/EIA-423-B  
(ITU v.10) and TIA/EIA-422-B (ITU v.11) standards is  
recommended.  
XXXXX  
The SN75185 is characterized for operation over the  
temperature range of 0°C to 70°C.
