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.
