The SN75ALS193 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.
This device meets the specifications of ANSI Standards EIA/TIA-422-B and
EIA/TIA-423-A and ITU Recommendations V.10 and V.11. 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 ± 200 mV over a common-mode input voltage range of –7 to 7 V.
It also features active-high and active-low enable functions that are common to the
four channels. The SN75ALS193 is designed for optimum performance when used with the
’ALS192 quadruple differential line driver.The SN75ALS193 is characterized for
operation from 0°C to 70°C.
