standards. These standards are for data

interchange between a host computer and

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

switching speeds of the ST75185 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.

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.

The ST75185 is characterized for operation over

the range of 0^oC to 70^oC.

The ST75185 complies with the requirements of

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