Order this document by SN75175/D The Motorola SN75175 is a monolithic quad differential line receiver with three–state outputs. It is designed specifically to meet the requirements of EIA–485, EIA–422A/23A Standards and CCITT recommendations. The device is optimized for balanced multipoint bus transmission at rates up to 10 megabits per second. It also features 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 SN75175 is 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 • • • • • • • • • • QUAD EIA–485 LINE RECEIVER WITH THREE–STATE OUTPUTS SEMICONDUCTOR TECHNICAL DATA Meets CCITT Recommendations V.10, V.11, X.26, and X.27 16 Designed for Multipoint Transmission on Long Bus Lines in Noisy Environments 3–State Outputs 1 N SUFFIX PLASTIC PACKAGE CASE 648 Common–Mode Input Voltage Range . . . –12 V to 12 V Input Sensitivity . . . ±200 mV Input Hysteresis . . . 50 mV Typ 16 High Input Impedance . . . 1 EIA–485 Unit Load 1 D SUFFIX PLASTIC PACKAGE CASE 751B (SO–16) Operates from Single 5.0 V Supply Lower Power Requirements Plug–In Replacement for MC3486 This device contains 174 active transistors.

All currents into device pins are shown as positive, out of device pins are negative. All voltages referenced to ground unless otherwise noted. 2. Differential input threshold voltage and guaranteed output levels are done simultaneously for worst case. 3. Refer to EIA–485 for exact conditions. Input balance and guaranteed output levels are done simultaneously for worst case. 4. Input resistance should be derived from input line current specifications and is shown for reference only. See EIA–485 and input line current specifications for more specific input resistance information. 5. Only one output at a time should be shorted.
