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. The
3-state outputs feature permits direct connection to a bus-organized system with a
fail-safe design that makes sure the outputs is always 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. The
device also features active-high and active-low enable functions that are common to
the four channels. The device is designed for optimum performance when used with the
SN75ALS192 quadruple differential line driver.The SN75ALS197 is characterized for operation from 0°C to 70°C.
