† 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.

Description

These four differential line drivers of SN55ALS194 and SN75ALS194 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 26 mA. SN55ALS194 and SN75ALS194 propagation delay time is less than 10 ns, and enable/disable times are typically less than 16 ns.

High-impedance inputs keep input currents low: less than 1 mA for a high level and less than 100 mA for a low level. The driver circuits can be enabled in pairs by separate active-high enable inputs. The SN55ALS194 and SN75ALS194 are capable of data rates in excess of 20 megabits per second and are designed to operate with the SN55ALS195 and SN75ALS195 quadruple line receivers.

The SN55ALS194 is characterized for operation over the full military temperature range of 55°C to 125°C. The SN75ALS194 is characterized for operation from 0°C to 70°C.
