Features include three–state outputs, thermal shutdown, and output current limiting in both directions. These devices also comply with EIA–422–A, and CCITT Recommendations V.11 and X.27. The MC75172B/174B are optimized for balanced multipoint bus transmission at rates in excess of 10 MBPS. The outputs feature wide common mode voltage range, making them suitable for party line applications in noisy environments. The current limit and thermal shutdown features protect the devices from line fault conditions. These devices offer optimum performance when used with the MC75173 and MC75175 line receivers. Both devices are available in 16–pin plastic DIP and 20–pin wide body surface mount packages. • Meets EIA–485 Standard for Party Line Operation • Meets EIA–422–A and CCITT Recommendations V.11 and X.27 • Operating Ambient Temperature: –40°C to +85°C • High Impedance Outputs • Common Mode Output Voltage Range: –7 to 12 V • Positive and Negative Current Limiting • Transmission Rates in Excess of 10 MBPS • Thermal Shutdown at 150°C Junction Temperature, (±20°C) • Single 5.0 V Supply • Pin Compatible with TI SN75172/4 and NS µA96172/4 • Interchangeable with MC3487 and AM26LS31 for EIA–422–A Applications PIN CONNECTIONS MC75172B MC75174B 9 1 3A 3Y 3Z En 12 4Z 4Y 4A VCC Gnd 2A 2Y 2Z En 12 1Z 1A 1Y P Package 2 3 4 5 6 7 8 16 15 14 13 12 11 DW Package 2A 8 7 6 5 4 4A VCC 19 18 En 2Z NC 10 11 9 9 10 11 12 13 14 15 16 8 7 6 5 4 3 2 P Package 1 3 En 17 4Y Gnd 2Y 12 3A 14 3Z 4Z 15 16 1A 1Y 2 1Z NC NC NC 3Y 13 20 1Y 1A 1Z En 2Z 2Y 2A Gnd VCC En 34 En 34 20 13 3Y NC NC NC 1Z 2 1Y 1A 16 15 4Z 3Z 14 12 2Y Gnd 4Y 17 9 2A 8 7 6 5 4 4A VCC 19 18 DW Package 2Z NC 10 11 4A 4Y 4Z En 3Z 3Y 3A 1 3 1 10 3A © Motorola, Inc. 1996 Rev 1 |
