DESCRIPTION
The ST75285 contains six drivers and ten 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^TM and compatibles. The
bipolar circuits and processing of the ST75285 provides a rugged low-cost solution for this
function at the expense of quiescent power and external passive components relative to the
ST75C185.

■ MEETS AND EXCEEDS THE REQUIREMENTS OF EIA/TIA-232-E AND ITUV.28 STANDARD
■ SINGLE CHIP WITH EASY INTERFACE BETWEEN UART AND SERIAL PORT CONNECTOR OF IBM PC/AT^TM AND COMPATIBLES
■ DESIGNED TO SUPPORT DATA RATES UP TO 120 Kbps
