description
The SN65175 and SN75175 are monolithic quadruple differential line receivers with 3-state outputs. They are
designed to meet the requirements of ANSI Standards EIA/TIA-422-B, RS-423-B, and RS-485, and several ITU
recommendations. These standards are for balanced multipoint bus transmission at rates up to 10 megabits
per second. Each of the two pairs of receivers has a common active-high enable.
The receivers feature high input impedance, input hysteresis for increased noise immunity, and input sensitivity
of 200 mV over a common-mode input voltage range of 12 V. The SN65175 and SN75175 are designed for
optimum performance when used with the SN75172 or SN75174 quadruple differential line drivers.
The SN65175 is characterized for operation from −40°C to 85°C. The SN75175 is characterized for operation
from 0°C to 70°C.
