bps (bits per second).

DESCRIPTION

The SN65LBC174A and SN75LBC174A are quadruple differential line drivers with 3-state outputs, designed for

TIA/EIA-485 (RS-485), TIA/EIA-422 (RS-422), and ISO 8482 applications.

These devices are optimized for balanced multipoint bus transmission at signaling rates up to 30 million bits per

second. The transmission media may be printed-circuit board traces, backplanes, or cables. The ultimate rate

and distance of data transfer is dependent upon the attenuation characteristics of the media and the noise

coupling to the environment.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
