ST75285 - ST Microelectronics

ST75285 MULTIPLE RS-232 DRIVERS AND RECEIVERS

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/ATTM and compatibles. The bipolar circuits and processing of the ST75285 provides a rugged low-cost solution for th.

Features

peripheral at signalling rates up to 20k-bits/s. The switching speeds of the ST75285 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. It allows space saving in applications where two ST75185 are needed. Comments 2500 parts per reel TSSOP3.
