SN55ALS192

These four differential line drivers of SN55ALS192 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 SN55ALS192 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 mA for a high level and less than 100 mA for a low level. Complementary 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 megabits per second and is designed to operate with the SN75ALS193 quadruple line receiver. The SN55ALS192 is also capable of data rates in excess of 20 megabits per second and designed to operate with the SN55ALS193; however, it may be limited to a lower bit rate based on the temperature (refer to the dissipation rating table and Figure 15).

The SN55ALS192 is characterized for operation over the full military temperature range of 55  to 125 . The SN75ALS192 is characterized for operation from 0  to 70 .
