description
The SN75174 is a monolithic quadruple
differential line driver with 3-state outputs. It is
designed to meet the requirements of ANSI
Standards EIA/TIA-422-B and RS-485 and ITU
Recommendation V.11. The device is optimized
for balanced multipoint bus transmission at rates
up to 4 megabaud. Each driver features wide
positive and negative common-mode output
voltage ranges making it suitable for party-line
applications in noisy environments.

The SN75174 provides positive- and negative-current limiting and thermal shutdown for protection from line
fault conditions on the transmission bus line. Shutdown occurs at a junction temperature of approximately
150°C. This device offers optimum performance when used with the SN75173 or SN75175 quadruple
differential line receivers.
The SN75174 is characterized for operation from 0°C to 70°C.
