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.
