descriptionThe 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 12 kΩ, 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.
