These 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 Recommendation V.11 and are compatible with 3-state TTL circuits. Advanced low-power Schottky technology provides high speed without the usual power penalty. Standby supply current is typically only 26mA. Typical propagation delay time is less than 10ns, and enable/disable times are typically less than 16ns.

High-impedance inputs keep input currents low: less than 1µA for a high level and less than 100µA for a low level. The driver circuits can be enabled in pairs by separate active-high enable inputs. The SN75ALS194 is capable of data rates in excess of 20 megabits per second and is designed to operates with the SN75ALS195 quadruple line receiver.

The SN75ALS194 is characterized for operation from 0°C to 70°C.
