ST75185C

Multiple RS-232 drivers and receivers

Features

■ 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/ATTM and

compatibles

■ Designed to support data rates up to 120 kbps

■ Pinout compatible with ST75C185

Description

The ST75185C 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

ST75C185.

The ST75185C complies with the requirements of

the EIA/TIA 232-E and ITU (formally CCITT) v.28

standards. These standards are for data

interchange between a host computer and

peripheral at signalling rates up to 20 k-bits/s. The

switching speeds of the ST75185C are fast

enough to support rates up to 120 K-bits/s with

lower capacitive loads (shorter cables). Inter-

operability 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 inter-operability 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.

The ST75185C is characterized for operation over

the range of 0°C to 70 °C.
