The SN751177 and SN751178 dual differential drivers and receivers are monolithic integrated circuits that are designed for balanced multipoint bus transmission at rates up to 10 Mbit/s. They are designed to improve the performance of full-duplex data communications over long bus lines and meet ANSI Standards TIA/EIA-422-B and TIA/EIA-485-A and ITU Recommendations V.10 and V.11.
The SN751177 and SN751178 driver outputs provide limiting for both positive and negative currents and thermal-shutdown protection from line-fault conditions on the transmission bus line.
The receiver features high input impedance of at least 12k , an input sensitivity of ±200 mV over a common-mode input voltage range of -12 V to 12 V, and typical input hysteresis of 50 mV. Fail-safe design ensures that if the receiver inputs are open, the receiver outputs always will be high.
The SN751177 and SN751178 are characterized for operation from -20°C to 85°C.
