description  
The SN75ALSI97 is a monolithic, quadruple line receiver with 3-state outputs designed using advanced,  
low-power, Schottky technology. This technology provides combined improvements in bar design, tooling  
production, and wafer fabrication. This, in turn, provides significantly lower power requirements and permits  
much higher data throughput than other designs. The device meets the specifications of ITU Recommendations  
V.10, V.11, X.26, and X.27. It features 3-state outputs that permit direct connection to a bus-organized system  
with a fail-safe design that ensures the outputs will always be high if the inputs are open.  
The device is optimized for balanced, multipoint bus transmission at rates up to 20 megabits per second. The  
input features high-input impedance, input hysteresis for increased noise immunity, and an input sensitivity of  
±300 mV over a common-mode input voltage range of –7 V to 7 V. It also features active-high and active-low  
enablefunctionsthatarecommontothefourchannels. TheSN75ALS197isdesignedforoptimumperformance  
when used with the SN75ALS192 quadruple differential line driver.  
The SN75ALS197 is characterized for operation from 0°C to 70°C.
