Quad EIA-485 Line Receivers
The Motorola SN75173/175 are monolithic quad differential line receivers
with three–state outputs. They are designed specifically to meet the
requirements of EIA–485, EIA–422A/23A Standards and CCITT
recommendations.
The devices are optimized for balanced multipoint bus transmission at
rates up to 10 megabits per second. They also 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 to 12 V. The
SN75173/175 are designed for optimum performance when used with the
SN75172 or SN75174 quad differential line drivers.
• Meets EIA Standards EIA–422A and EIA–423A, EIA–485
• Meets CCITT Recommendations V.10, V.11, X.26, and X.27
• Designed for Multipoint 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 . . . 1 EIA–485 Unit Load
• Operates from Single 5.0 V Supply
• Lower Power Requirements
• Plug–In Replacement for MC3486 (SN75175)
AM26LS32 (SN75173)
