description nThe SN55173, SN65173, and SN75173 are monolithic quadruple differential line receivers with 3-state outputs. They are designed to meet the requirements of TIA/EIA-422-B, TIA/EIA-423-B, TIA/EIA-485-A, and several ITU recommendations. The standards are for balanced multipoint bus transmission at rates up to 10 megabits per second. The four receivers share two OR enable inputs, one active when high, the other active when low.nMeet or Exceed the Requirements of TIA/EIA-422-B, TIA/EIA-423-B, and TIA/EIA-485-A and ITU Recommendations V.10, V.11, X.26, and X.27 nDesigned for Multipoint Bus Transmission on Long Bus Lines in Noisy Environments n3-State Outputs nCommon-Mode Input Voltage Range of –12 V to 12 V nInput Sensitivity... ±200 mV nInput Hysteresis. . . 50 mV Typ nHigh Input Impedance. . . 12kΩ Min nOperate From Single 5-V Supply nLow Power Requirements nPin-to-Pin Replacement for AM26LS32
