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 26mA, while typical propagation delay time is less than 10ns. High-impedance inputs maintain low input currents, less than µA for a high level and less than 100µA 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.
