description
The SN75ALS199 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, providing significantly less power consumption and permitting much higher
data throughput than other designs. The device meets the specification of ITU Recommendations V.10, V.11,
X.26, and X.27.
The SN75ALS199 features 3-state outputs that permit direct connection to a bus-organized system with a
fail-safe design that ensures the ouptuts 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. It also features an active-high enable function for each of two
receiver pairs. The SN75ALS199 is designed for optimum performance when used with the SN75ALS194
quadruple, differential line driver.
The SN75ALS199 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 conditions” 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.
