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.

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.
