description
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.

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditons is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability .
NOTES: 1. All voltage values, except differential input voltage, are with respect to network ground terminal.
2. Differential-input voltage is measured at the noninverting input with respect to the corresponding inverting input.
