description

The four differential line drivers are designed for data transmission over twisted-pair or parallel-wire
transmission lines. They meet the requirements of ANSI Standard EIA/TIA-422-B and ITU
Recommendations V.11 and are compatible with 3-state TTL circuits. Advanced low-power Schottky
technology provides high speed without the usual power penalties. Standby supply current is typically only
26 mA, while typical propagation delay time is less than 10 ns.

High-impedance inputs maintain low input currents, less than 1 µA for a high level and less than 100 µA for a
low level. Complementary output-enable inputs (G and G

) allow these devices to be enabled at either a high
input level or low input level. The SN75ALS192 is capable of data rates in excess of 20 Mbit/s and is designed
to operate with the SN75ALS193 quadruple line receiver.

The SN75ALS192 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.

¶

|VOD| and |VOC| are the changes in magnitude of VOD and VOC, respectively, that occur when the input is changed from a high level to a low level.

#

In ANSI Standard EIA/TIA-422-B, VOC, which is the average of the two output voltages with respect to ground, is called output offset voltage,
VOS.

||

Not more than one output should be shorted at a time, and duration of the short circuit should not exceed one second.
