MOTOROLA ANALOG IC DEVICE DATA
Quad EIA-485 Line Receiver
The Motorola SN75175 is a monolithic quad differential line receiver with
threestate outputs. It is designed specifically to meet the requirements of
EIA485, EIA422A/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 EIA422A and EIA423A, EIA485
Meets CCITT Recommendations V.10, V.11, X.26, and X.27
Designed for Multipoint Transmission on Long Bus Lines in Noisy
Environments

NOTES: 1. 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 EIA485 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 EIA485 and input line current
specifications for more specific input resistance information.
5. Only one output at a time should be shorted.
