Product Summary
The ST75185C is a multiple RS-232 driver and receiver. The device 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 ST75185C. The ST75185C complies with the requirements of the EIA/TIA 232-E and ITU (formally CCITT) v.28 standards.
