ST75185CN Datasheet - STMicroelectronics

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.

■ MEETS AND EXCEEDS THE REQUIREMENTS OF EIA/TIA-232-EAND ITUV.28 STANDARD
■ SINGLE CHIP WITH EASY INTERFACE BETWEEN UART AND SERIALPORT CONNECTOR OF IBM PC/AT AND COMPATIBLES
■ DESIGNEDTO SUPPORT DATA RATES UP TO 120 Kbps
■ PINOUT COMPATIBLEWITH ST75C185
