SN75ALS192 QUADRUPLE DIFFERENTIAL LINE DRIVER SLLS007D – JULY 1985 – REVISED APRIL 1998 D D D D D D D D OR N PACKAGE (TOP VIEW) Meets or Exceeds the Requirements of ANSI Standard EIA/TIA-422-B and ITU Recommendation V.11 Designed to Operate up to 20 Mbaud 3-State TTL Compatible Single 5-V Supply Operation High Output Impedance in Power-Off Condition Complementary Output-Enable Inputs Improved Replacement for the AM26LS31 1A 1Y 1Z G 2Z 2Y 2A GND 1 16 2 15 3 14 4 13 5 12 6 11 7 10 8 9 VCC 4A 4Y 4Z G 3Z 3Y 3A 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.
