Quadruple Differential Line Receiver

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.
