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.
