SN75175DRE4 Datasheet

RS-422/RS-485 Interface IC


The SN65175 and SN75175( SN75175DRE4 ) 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. SN75175DRE4 Features • Meet or Exceed the Requirements of ANSI Standard EIA/TIA-422-B, RS-423-B, and RS-485• Meet ITU Recommendations V.10, V.11, X.26, and X.27• Designed for Multipoint Bus Transmission on Long Bus Lines in Noisy Environments• 3-State Outputs• Common-Mode Input Voltage Range −12 V to 12 V• Input Sensitivity . . . ±200 mV• Input Hysteresis . . . 50 mV Typ• High Input Impedance . . . 12 kΩ Min• Operate From Single 5-V Supply• Low-Power Requirements• Plug-In Replacement for MC3486
